Vue React 2021

Posted on  by admin

Vue.js and React.js are JavaScript-based toolkit systems. They help build dynamic user interfaces. Regarding their concept, the whole UI is the data, and every change leads to new functions.

These functions are refreshing certain page blocks, commonly known as UI components. In Vue.js and React.js, components are the pieces of JavaScript and HTML code organised into one file.

The components have similar hierarchy principles, with parents and children, who could pass the data to each other. To find out the distinctive features between React and Vue.js, we should take these criteria into account:.

How the components are created with React and Vue.js;. How the components communicate with each other;.

How the components impact the browser DOM. So, knowing that, we will be able to make a choice. Needed to mention that React could not be called a framework, but it has always been considered so.

Even though it is a JavaScript library, it is suited to build an entire view part of the web application.

  1. Components render the data on web browsers.
  2. They include the UI part, which is shown to a user (HTML) and logic (JavaScript).
  3. The logic describes functions and methods to communicate the data in the browser.
  4. React uses JavaScript Syntax Extension (JSX), a syntax language that helps write functions corresponding to native methods of browsers.
  5. Safari, Chrome and Firefox are based on JavaScript engines that can directly talk with the logic functions written in React.

Vue vs React: Meet the contestants

Since JavaScript code is enriched with HTML tags, it can't be recognized by a web browser. So, React is converting the programming code to pure JavaScript, using Babel Transpiler.

JSX allows to return HTML in JavaScript, or it could be executed in HTML. Also, JavaScript variables can be assigned with HTML tags, like this:.

Dynamic variables could be put into bracket syntax ( { .. } ) in the middle of JSX. An example of React component, written with JSX (image source link).

According to Stackshare statistics, the most favourite features of React are components (747) and simplicity (484). JSX, though, takes less user appreciation (31).

I think the biggest concern about JSX is that it doesn't require a specific code structure. The logic and UI of components are in one file so that it could lead to messy code.

Round 9: State Management

The idea of the single-file component is opposed to Angular, which proposed keeping HTML, JavaScript and CSS in separate files.

Completing components in a single file didn't get enough popularity unless Airbnb and Netflix joined the React community and began using React for their MVP construction.

When searched for materials related to our topic, I found the 'Do Better Dev Show podcast'. In one of their episodes, Nathan Calvank and his co-host Gyanesh Mishra discussed the main difference between Vue and React.

In the middle of the podcast show, Nathan shared his technique of code adjustment in React:.

  1. Vue.js follows HTML templates for the component design

    "JSX combines logic and presentation. You have got your HTML alongside your JavaScript in the same component. The way it is separated now: you have all your logic at the top, and you just return all your JSX below that.

    If you have a sufficiently complex application, you can pull out all of that logic to a container. The container holds all that logic and loads components, including this logic".

    You will get the benefit of JSX, getting the separation of concerns from the development side. So, dealing with the potential frustration of those things combined, this is a reasonable way of keeping these things separated".

    You can listen full podcast here. The same as React, Vue.js proposes keeping the UI and logic in the same file. The component code in Vue.js is contained within a specific HTML template.

    The templating brings a clear image of the component code. It helps programmers keep an eye on the methods, view the properties and observe the render functions.

    Vue.js has a specific syntax. It uses double braces {{ }} as place-holders for data.

  2. Summary:

    HTML attributes are the directives in Vue.js and contain the prefix v-. The framework's system involves objects, classes and behavior categories.

    It matches with the experience of programmers who had worked with object-oriented programming.

  3. What companies should choose Vue.js:

    In the meanwhile, Vue.js enables writing with JSX, which extends the programmatic power of the framework. React requires solid JavaScript skills, while Vue.js is more oriented to novice developers.

    • Similar to React, Vue.js enables writing with JSX, but the components are written with HTML templates.
    • When a user opens the web page, the Internet browser parses it to a tree-like structure and reads it up to down.
    • This tree-structured file is called the Document Object Model (DOM).
    • If the user did some action on the page, the browser needs to recreate and re-read the DOM.
  4. Ecosystem

    It takes more loads and decreases the resources of the browser.

    React avoided the traditional DOM rendering and leveraged the capacity of data rendering in the browser. Pete Hunt, a core member of React team, described the idea for the InfoWorld magazine:.

    "The browser itself is retain mode. You click an HTML element on the screen, and then you change it over time. The programming model we wanted for React was basically to throw out and redraw everything.

    We think that's easier to understand. However, the browser is not designed to work like that.

  5. Learning Curve

    What we did is we built something that we're calling the virtual DOM to abstract that.

    And so we have a way of basically rendering to a virtual DOM, throwing out the whole virtual DOM and re-creating it every time the data changes, and then React under the hood will convert that, will get the old virtual DOM with the new virtual DOM and then convert that to manipulations of the real browser DOM".

Thank you, Pete.

Based on your explanation, we could figure out how does the Virtual DOM operates:. Before the web page is loaded in the web browser, React makes a copy of the DOM and places all the objects in a new component.

Round 8: Security

When a user opens the web page, React doesn't access a real DOM but renders the copy of DOM.

It is called the Virtual DOM. While the user walks through the page, React is computing the changes. If the user clicked a button or performed any other action, React creates a new snapshot of the DOM and compares it with the previous version.

If one more node element has changed, React updates the page rendering the real DOM. Amazingly, that React team kept in mind an idea of the game engine when developed the virtual DOM:.

The difference with React is the way that your program is much more like a game engine, as opposed to these alternative approaches, withSome of you might know that virtual DOM allows us to compare two snapshots of your view structure and figure out what actual changes you should apply to the DOM.

In most cases, it is relatively cheap and fast. However, there is still a cost because you are recreating lots of JavaScript objects.

You have to walk through the whole tree on each update to figure out what has actually changed. And it counts pounds as your application gets larger.

But the worst part about the virtual DOM is no matter how little dynamic content you have in your template, you always have to walk through the whole tree to find out what has exactly changed".

Round 7: Performance

Vue.js is now tracking the dependencies within each object of the DOM tree. The virtual DOM in Vue 3.0.11 is tracking the dynamic elements only, which contain


Templating in Vue.js helps to represent a mini-DOM of a component. Instead of tracking each object, Vue.js goes over the dynamic parts in templates.

So, it sufficiently optimized the operation of virtual DOM and leveraged the client-side rendering in Vue.js projects. Virtual DOM in React needs to track all the nodes in the tree, whether they are static or dynamic.

While looking through the articles comparing React vs.

  1. React renders data through the virtual copy of browser DOM

    Vue.js, you could find different views regarding the data binding. You could often read that React follows just a one-way data flow.

    Meanwhile, Vue.js provides just the two-way binding like Angular. That is not true. Both React and Vue.js support the one- and two-way data flow simultaneously.

  2. Articles and tutorials

    Moreover, they suggest the one-way data flow as most preferred. Let's get a look at the piece of documentation on Vue 3.0.11 that emphasizes the benefits of one-way.

    Even though React components are designed for one-way flow, they could work with the two-way direction. React supports callback functions so that the children components could fetch the props to their parents.

    For example, if a user is typing the text in the input field of the child component, these changes will reflect the parent and update its content.

    With that said, the React community is provided with react-hook libraries, which enable two-way data binding. Vue.js and React support one-way as well as two-way data binding for components.

    In general, one-way data flow helps establish better control of the project functionality.

    Both frameworks recommend it as the best option. React.js is flexible and open to a variety of choices. It doesn't imply any opinionated direction or mentality for development.

  3. Summary on comparison of the virtual DOM processing:

    However, this approach has some cost because the developers need to have a strong knowledge of JavaScript and be experienced with Single page applications (SPA) design.

    Fast client-side rendering. Good control of the data flow. Light-weight architecture. Extensibility and scalability. Large community support. Steep learning curve.

    Does not operate without other libraries and services, like Redux, routing, etc.

    Structure-free code may get to spaghetti and boilerplate.

  4. Who's Using React and Vue

    Early-stage startups that need fast feature development and validation campaigns on the market.

    Companies that are looking to outsource their development. It is much easier to find a React developer compared to the one with Vue.js expertise.

    Product-based companies will also require cross-platforming app development (React Native based on React technology, that it will be a good fit).

  5. Architecture

    Vue.js combined the top-level features of React and Angular, but its main feature is the perfect user experience.

    Also, it leveraged the capacity of the virtual DOM and optimized the code structure. Developer-friendly framework. Outstanding performance.

    Well-structured code. Elegant language syntax. Fine user documentation. Lack of experienced developers. Small community. A big part of the documentation is written solely in Chinese.

  6. Create both web and mobile apps

    Companies that approach the market of web-based products. Companies that are looking to implement a single flow in their development process.

    Companies with no previous experience of using frameworks in their build process or those looking to leverage their proficiency with JavaScript.

  1. What companies should choose React:

    Tech Talk: 1 vs 2 way Data Binding in React and Angular (Matthew Elmquist for Fullstack Academy). Although Javascript Frameworks are now a staple in the world of web app development, more and more companies are getting used to how they can improve both performance and time savings while improving the overall development experience.

    However many other companies and devs still struggle with choosing the right framework. What we know Currently is that React.js has been on the top spot on the podium for three successive years, while Vue.js is second.

    So how do you decide which framework fits for you considering that both of them are in the same league when it comes to popularity?You are in for some luck.Because for this article, we are aiming to make a head-to-head comparison between React and Vue.

  2. React

    **we’ll explore what their respective use cases are, along with perks that Both of them bring to the table. What is Vue?**Vue Is a front-end framework that has garnered immense support from its community, after Being developed and showcased by the talented developer named Evan You in 2014.

  3. Summary of the requirements:

    Vue was primarily used exclusively in China, but is now used worldwide and has turned out to be among the best options for developing intuitive and interactive user interfaces as well as creating single-page applications.

    Vue is known for its two-way-binding feature and its unique way to manipulate the DOM by using a virtual DOM, but the primary reason Vue easily rose to prominence is its progressive design which lets developers migrate and smoothly move pre-existing projects.

  4. 1. FeetUp®

    This is possible by moving each feature, one at a time. Considering that Vue is an open-source project that got a good start and is still maintaining its dominance as being one of the most accessible frameworks out there, Vue has become more and more associated with many other big names that had to implement web development into their business.

    Even though React is considered a framework it's actually a javascript library used for web development to create interactive elements for websites and User interfaces.

    The creator of React is a former employee of Facebook and is named Jordan Walke.

  5. Development and Popularity

    React was released in 2013 which was a time when javascript made major strides in how it functions and operates as a programming language, and as a result, react had a lot of room for innovation.

    React is used in the creation of single-page apps and mobile apps through its flexibility and usage of components which isolates pieces of code and makes the components reusable on different parts of the web app.

7. SEO: Vue vs React

  1. Table of content

    React also uses the visual Dom to interact with the DOM but all the elements are represented as javascript objects. This is a declarative, highly efficient, and very flexible library that brings a lot of toolsets to any developer looking to pick up a new framework.

    React is the leading framework as its the most used and most in-demand on the work market, and as such, it has on many occasions been associated with names of big companies out there, some examples of websites that use react are Facebook, Netflix, and Instagram.

  2. 2. Habitica

    How do Vue and React differ in popularity, performance, and state management? Both Vue and React utilize Lazy loading resulting in higher performance and lower loading time and they also share the fact that they both use the Virtual DOM to update the DOM.

  3. Pros of Vue.js:

    Now, let's take a look at Vue first, It has better memory allocation and faster startup, no unnecessary re-rendering because vue keeps track of the virtual DOM, it handles higher frames than react(up to 10 frames/second).

  4. JSX and single-file component structure in React

    It's More popular than react on GitHub based on stars given but less popular on StackOverflow based on the yearly surveys.

    with Vue You can edit the data through the data property, so you don't need the local state.

    However, If you have big apps, you'll need a separate library to manage the state. Now let's shift our look unto React. React have faster runtime, changing state re-renders all of the components in the virtual dom, handles low frames at 1 frame/second.

    More popular than Vue on StackOverflow surveys, but less popular on GitHub, more popular in the job market.With React, you can modify the state in just one place, simplifying debugging.

Round 1: Popularity & Support

5. Vue vs React state management

  1. Develop a pocket-size, quick app

    Differences in syntax and community support: Vue vs React. Programming style: Vue makes component life cycles more intuitive and keeps HTML, CSS, and javascript code separate.

    React embeds HTML code into javascript and generates javascript expressions(JSX), and also allows every component to have its own lifecycle.

    -Community support: Vue was highly popular in China when it came out on the market and has further garnered more support around the globe hinting that Vue will just keep on growing.

  2. 1. FontAwesome

    React however is backed by Facebook and has a dedicated team of developers maintaining it. -Documentation: Vue's documentation is very clear and concise.

    It's organized much better than most other frameworks docs. While React's documentation has improved over the years and is more clear, when it came out, it got criticized for its bad documentation.

  3. Pros of React:

    -Learning Curve: Vue is easier to learn and intuitive for beginners because it separates HTML, CSS, and javascript, so anyone with vanilla javascript experience will have no trouble getting familiar with it.

    When it comes to learning time, React takes more time to learn than Vue because of some new concepts not seen in regular javascript.

    -Syntax: Vue uses HTML and JSX while React is strictly JSX. -SEO: Google has a hard time indexing single-page apps, which means by default Vue and React can't be indexed.

  4. Videos on YouTube:

    This can be solved by using server-side rendering, which lets us run the JS code on the server before sending our files to the end-user.

    Which one is better, Vue or React? You should use Vue if:. You need a quick solution-you need your app to run fast-An existing project needs to be migrated to a new technology but you've got limited resources-Most of your team consists of junior developers or HTML developers-you're into clean code-You want to create less complex to medium complex apps(there are always exceptions).

    React is for you if:. -You want to create a moderately to a highly complex app or SPA-In the future, you'll expand your applications' capabilities a lot-you need to make mobile applications-JavaScript is preferred over HTML-Your team is comprised of experienced React developers.

Both frameworks Come out of the box with their advantages.With Vue, it's smaller, faster, templates are convenient, a simplified syntax, etc.

Meanwhile, React offers more flexibility for bigger, more complex apps. You'll be able to test it better, and it's more suitable for mobile app development.

    JavaScript developers can use React and Vue.js to build front-end applications or rich user interfaces that run on the client-side via a web browser.

8. Which is better, Vue or React?

Introducing React and Vue.js

They are both based on familiar patterns, such as components, but they're not entirely identical. In the beginning, there was a debate between developers if they should choose Angular or React. However, recently, Vue.js was added as another library that front-end developers should consider when developing their apps due to its constant growth.

9. Will Vue replace React?

React was initially developed for Facebook and first released in 2013, and it's still being developed and maintained by the tech giant. It's available under MIT license, a permissive open source license that many web tools are using.

Useful resources

Vue was initially developed by Evan You, who was an ex-Google developer working on the Angular team. It's influenced by the most popular and modern libraries/frameworks such as Angular, React, and Ember. It's an open-source project maintained by the community.

Data binding of the components

As stated by Evan You:. What if I could just extract the part that I really liked about Angular and build something really lightweight.

Vue, or also Vue.js, is younger than React. It was released in 2014. Since then, Vue has been steadily growing in popularity and became competitive to React, which is an impressive thing since it doesn't have the resources of a company like Facebook.

While both libraries are open-source projects released under MIT, React is backed by a giant company, while Vue.js relies on crowdfunding and contributions from the community.

MIT is a very permissive license, but you should always understand the license before using a library. Here is a summary of the MIT license in easy English.
