Introducing the React.js framework, its features and benefits

React.js is a popular JavaScript library that is for web applications with very attractive user interfaces. This library is also for managing display layers in web and mobile applications.

React.js works great in some areas, such as creating websites with a great user interface, as well as making settings and making changes to the website in the shortest possible time. But in some cases, such as making games, it may not be a good option.

React.js allows the developer to create a great user interface for complex applications, which often require multiple, reusable components to show on the screen.

In contrast, React can not create quality characters when making a game and is therefore not suitable for making a game.

Features of React.js

The React.js framework has the following three main features:

  • Use declarative view
  • It is based on a set of components that can manage their various states.
  • Its code can be for different technologies (laptops, tablets, etc.) and browsers.

Let’s see what each of these features means:

1- Using news view

In general, there are two types of programming, one grammatical and the other news. In grammar programming, a series of special steps are for achieving the desired goal by doing them. So news programming refers only to a set of principles and generalities about data, and does not discuss commands or execution steps (what to do).

Let’s take a look at the following example of making a burrito:

Suppose you want to make a burrito grammatically. First you have to make Mexican corn, chop the vegetables, cook the meat, grate the cheese and then add all these ingredients to the corn, roll them and then taste.

But in contrast, in the news method, only a series of principles are for you. The consumer does not need to do the above steps one by one, for example only the required vegetables, proteins and cheeses are given and these materials are used as input.

In React applications, because of the use of news programming, the written code is easily predictable and easier to troubleshoot. In addition, the app knows when to re-display the page (based on data it receives from input).

2- Made based on components

React websites are for using components that are reusable blocks for a web page.

If you only use one specific component, you can reuse this component, but be aware that it provides different information.

Conceptually, components are something like JavaScript functions that give you a different output depending on the input, in this case; HTML output is on the screen.

Another important concept that exists about components is the concept of State. Each component monitors its own state, the state actually tells you what your page will show.

You should note that each state belongs only to its own component, unless you transfer this state to component subdivisions for a specific purpose.

States act as one of our sources for validation, meaning that the information of a component is placed only within its specific state and is not transmitted to other states.

We transfer information from the main components to the sub-components as a props. These props can be thought of as levels for checking parameters in JavaScript.

Props can receive any type of JavaScript data (from a loop to a function). The programmer can decide whether he or she needs to transfer information from the original component to the sub-component according to his or her wishes.

The most important thing to know about props is that props can only be transferred to sub-components and cannot be transferred from subsets to main components. Like a waterfall, props can move down, but they cannot overcome gravity and move up.

3- Reusability

React.Js code is written the same for all browsers and technologies, React apps can also be programmed on different platforms.

For example, a developer can easily create mobile applications using React Native, and React can also create a mobile app framework.

Due to the increasing importance of browser responsiveness and increasing competition between different browsers and devices, React reusable code is now being entered more manually.

Benefits of the React.js framework

In the following section, we will examine the areas in which React.js has many uses. If we want to mention the 10 main applications of React.js; We must state the following:

1- Creating dynamic (animated) browser applications is easier.

In the past, creating a dynamic browser page required complex coding. Creating dynamic web pages requires special HTML loops. Using React.js solves this problem. React.js uses JSX. In addition, machine-readable code generation is supported, and components are into a special variable file. React does not use the usual JavaScript to build templates.

2- Increases fertility and helps you maintain it.

Reusing components is the best advantage of React.js. Even Facebook uses React to make it easier to reuse system components. The programmer can start with simple components such as checkbox and button. Once you have done this you can then move on to other components and make it easier to use them.

This helps to increase the stability of the application and maintain its stability. Many companies like Walmart are interested in using it. Each company has its own components such as payment gateways and so on. There are also standard codes for activating the admin version as well as installing additional components that can maintain the uniformity of the collection. This also increases the speed of the app, which makes the user more satisfied.

3- Faster display of virtual DOM

The performance of any application depends on the structure on which it is created. When building an application, the fast loading of the application is one of the most important factors to consider. But the engines used today have limitations because the DOM has a triple structure and even the smallest layers can make a big difference. To solve this problem, a virtual DOM was introduced. React.js can be used when a program is loading late.

A virtual representation is used on the model and it examines the changes if you apply them to the virtual DOM. The actual DOM was added later and is used to estimate the minimum time required to achieve this goal.

4. Make sure you have a stable code

In React.js, data is transferring downwards. The reason for this is that if the slightest change occurs in the sub-components, the main components will not be affected. When a programmer wants to change his goal, he must make sure that only that specific goal has changed and only that specific mode has been modified. The data is limited according to the purpose, and this helps maintain the operational stability of the application.

5- Flux, Redux architecture

The Flux architecture was introduced by Facebook for its various applications on the web. This architecture is similar to React components that flow in only one direction. This architecture has operators that help to create an action in the method parameters. The architecture also maintains a library for these methods.

All these actions are together by one distributor. You can update all views according to the reserves. Redux is also an updated and advanced version of flux. In this version there is a warehouse that does not exist in flux. Redux also has the property that you can define a middleware for actions.

6- React.js Has positive characteristics in the field of SEO

When a search engine fails to read JavaScript, React.js runs on a server at the same time and returns and displays the virtual DOM through a regular web page. With it, you can deal with this inability to read JavaScript. Although there is a lot of progress in Google today, we can not ignore search engines such as Yahoo, Bing, etc., as well as microformats such as OpenGraph, Twitter, etc.

7- A useful development tool

Another benefit of React.js is having an extensible platform. The two main tools in this field are react developer tool, redux developer. Both tools can be as extensions to Google Chrome browser. The react developer tool is for examining the components that are in a set, and it is also for examining the properties and states.

You can also view the hierarchy of components and also identify the main components and subsets. When using redux you can see different actions, you can also see the current saved states and changes on the stocks. You can also see different actions or modifications of stocks in this section.

8- React.js is very useful in the development of mobile apps.

React helps you create a similar design pattern so that there is not much difference between the process of creating a web and a mobile app. Using JavaScript and React native, you can create good UI applications that run on both Android and iOS systems.

9- Easy to learn

It is not a framework, but a library that focuses on a single goal and strives to achieve it. Any programmer familiar with JavaScript can easily understand React, learn its basics, and design a great website.

10. More than 500 companies use React.js

React is all over the world for simplicity. Most companies will want to hire you when you learn to work with it. Companies like Airbnb, Tesla, etc. use React Native for their apps.


Considering all the benefits mentioned for React.js, we can say that React.js is completely reliable, responsive and professional. You can easily create great websites and constantly make changes to them. Virtual DOM, which is also very fast, helps programmers a lot.
