React Vs Vue 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.

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

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.

Round 1: Popularity & Support

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.

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:.

Vue.js vs. React — What Are They?

"JSX combines logic and presentation. You have got your HTML alongside your JavaScript in the same component.

Round 2: Talent Availability

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".

Round 4: Ecosystem and tooling

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