If you are working as a specialist in the field of programming, you are probably familiar with titles such as React JS, JSX, and JavaScript. But if you are someone who is just going to enter the field of programming, you should get general information about what was said in this field. Stay with us in this article to explain these things.

What is JavaScript?

JavaScript is a programming language used to create dynamic elements in web pages and web applications. All modern browsers today support this language. Almost all web pages have many features created by this language such as form validation, advanced animations, pop-up windows, etc. JavaScript is used to create web applications and user-side pages.

JavaScript has quickly taken over the world. According to StackOverflow’s annual reports, for the fifth year in a row, JavaScript is the most used language in the world. And all the evidence indicates that this process will continue in the coming years.

But what is React?

React is a library for creating a user interface that is developed by Facebook and its user community.

For example, in MVC architecture, React is usually used in V or View.

React features include the following:

JSX Syntax: It is not mandatory to use this syntax, but it is recommended to use it to use HTML and XHTML in JavaScript as easily as possible.

Components: If you consider everything as a component in React, you can maintain your code better in the future.

Flux pattern and unidirectional data flow: Unidirectional data flow means that all data in the program follow a life cycle, which makes your program logic more understandable.

Among the advantages of React, the following can be mentioned:

Using virtual DOM as an object improves the performance of the program compared to using normal DOM.

It can be used on client-side and server-side as well as with other frameworks.

Component and data pattern improves the readability; it also helps to maintain large programs.

What is JSX?

JSX stands for JavaScript XML. React uses JSX for templating, instead of regular JavaScript codes, it is not necessary to use it, but it has advantages, some of which we will explain below:

JSX is faster because, in addition to compiling the code to JavaScript, it also optimizes the code.

JSX has a type-safe feature; That is, it prevents the creation of errors in all types of data, identifies errors during compilation, and makes the implementation of templates easier.

Reasons to use React js

Now, the most important question we come across is why should we use React js.

There are many open-source platforms for easily building front-end web applications, such as Angular. Let’s take a look at some of the advantages of React over other competing technologies and frameworks.

Considering that there are many changes in front-end programming in the world every day and it is very difficult to allocate time to learn a new framework, especially when that new framework will eventually become obsolete. So, if you are looking for the best option for the future, but are confused among the multitude of frameworks, I suggest you check out React.

The simplicity of React js

React js is so simple that you can understand it properly. The component-based approach ensures the application lifecycle, and the use of the JavaScript framework has made React very easy to learn to easily design and support professional web and mobile applications.

React uses a special language called JSX that allows you to integrate HTML and JavaScript. It is not necessary to use this method and the programmer can also use simple JavaScript, but JSX will make things much easier.

Easy to learn

React can be easily learned by anyone with a basic knowledge of programming, while Angular and Ember, referred to as “domain-specific languages”, meaning they are difficult to learn. In general, to learn React js, you only need basic knowledge of CSS and HTML.

A native Ruiker

React can be used to design mobile applications (React Native). React is a strong proponent of reusability in the sense that it supports extensive code reusability, so at a given time we can produce both an Android app, an IOS app, and a web app.

Data connection

React uses a one-way data connection and an application architecture called Flux to control the flow of data to components through a distributed control point, allowing large applications built in React to run autonomously. Make it easy to troubleshoot components.
