Over the past few years, React.js has emerged as a popular framework used to develop effective web applications. If you’ve spent any time working with JavaScript, chances are you’ve heard the word React at some point.

React.js, developed by Facebook, is a JavaScript library for building user interfaces. React makes it easy for developers to create and aesthetically pleasing interactive user experience for websites.

According to Stack Goal developer survey 2019 , React.js is the most beloved web framework among developers. React is so popular that sites like Facebook, Codecademy, and New York Times are all built using the React framework.

This Guide discussing the best way to learn programming using React online. We are going to pass what you need to know to start your React learning journey .

What is JavaScript?

Before discussing it in React, we need to talk about two concepts: front-end development and JavaScript

There are two main components of ’a website: front-end and back-end. The front-end is what the user sees on a site. The back- end is what the users do not see, such as scripting forms in e process on a site.

The backend and the frontend code come together to create a website. Along with HTML and CSS, JavaScript is a foundational technology used for front-end web development and allows you to create dynamic web content.

What is React?

React.js is an open source JavaScript library. It is used to create user interfaces and components for a web page. Facebook and the open source community maintain React.js

You can group parts of a website into components with React, which are small blocks of construction for your application. Questo approccio alla codifica basato su componenti ti consente di ridurre la ripetizione nel tuo codice e migliorare la velocità di un’applicazione web.

La libreria React √® forse la libreria JavaScript pi√π popolare al mondo grazie alla sua semplicità d ’Use. React is businesses ranging from Facebook to Netflix and Slack.

React uses JSX (which is short for JavaScript Extension) which makes it easy to write an efficient web using HTML like syntax. In the second place , React offers a feature called virtual DOM, which, without going into too much detail, accelerates sites loading.

Do you need to study React?

Learning to code in React.js is a great investment of your time for any budding front-end web developer . But why is it so? First of all, a wide variety of large organizations use React, from the New York Times to Facebook. If you know how to code in React, you will have a great skill that you can list on your resume.

Second , React it makes it easy to develop modern web applications. React offers features like declarative syntax and a wide range of external libraries that allow you to build powerful web experiences.

React has become more popular, an increasing number of raw resources have emerged . This should make it easier for you to get started.

React is used for front-end web development. This is the side of web development that is building the part of a website that the user sees.

Backend Development, on the other hand, is the "brain" behind a website.

React allows developers to create reusable components for the front. This brings more structure to a front-end website writing process and helps reduce code duplication.

How long to take to learn ReactJS?

In short, becoming proficient with the basics of React will take one to six months. The exact time to master React depends on your software development experience and how much time you are willing to devote to learning.

If you spend 10 hours per week learning React, you will learn to use the library much faster than you would if you spent less time learning. If you spend two hours learning React Day, you should be able to master the fundamentals within a few months.

These time frames do not take into account the time it takes to learn you would react if you didn’t have experience programs. Since React is a JavaScript framework, the first thing you need to do is master the fundamentals of JavaScript. Then you’ll be ready to start some research on how to program using React.

is React hard to learn?

If you find it hard not to learn the basics of React as long as you are familiar with coding in HTML, CSS, and JavaScript.

While React has its own unique ecosystem and development practices, you don’t need to be an expert programmer to get started. Your knowledge of general web development practices will take you a long way.

The more familiar you are with web development, the easier it will be for you to learn React. It helps if you have experience using another framework, such as Angular. This is because you will have a better understanding of how frames relate to the broader JavaScript language.

Learn to react quickly

Are you convinced that learning to react is a good use of your time? Great! There is one question to answer: How can you learn to react quickly

First , we will discuss the main skills you need to know when it comes to reacting. Next, we’re going to talk about how you can actually learn these skills

Develop your skills

Learning to program using React.js is a little different from learning to ’ linguistic programming. This is because unlike technologies such as CSS or HTML, React is a library that is part of another programming language:. JavaScript

To help you on your journey, we’ve compiled a list of the best skills you have. I’ll have to build.

Learn HTML, CSS, and JavaScript

Before you can program using React, you need to learn HTML, CSS and JavaScript.

Although HTML and CSS are not required, the JSX syntax used by React is based on HTML. You will need to have a good knowledge of HTML to understand how it works. When it comes to JavaScript, React is based on JavaScript, so there’s no way to learn JavaScript programming.

You need to know the basics of JavaScript and have a good understanding of HTML and CSS to get started with React. Your best bet is to focus on learning JavaScript ES6 or later. This will give you a good foundation on which to build your JavaScript skills. This should be in addition to learning the basics of HTML and CSS

Here are some resources you can use to learn about the basics of HTML, CSS, and JavaScript.


JSX or JavaScript expression, is a ’syntax extension for JavaScript written for use with React. The JSX technology allows you to describe what a user interface should look like a website. You should start learning React by exploring how JSX works. Find out how you can use JSX to create elements in a user interface.

Here are some topics you should explore to deepen your understanding of JSX:.


Routing, in layman’s terms, shows how users access your website. It is a tool that links URLs and your application. Consider this example. You are on your home page and you have clicked and gone to your bio page. This is routing in action.

React Router allows creating a single page web application without refreshing the page the user is currently browsing . The router uses a structure constituting call components, which contains and displays the appropriate information.


Components are the building blocks on which all JS React based applications are built. All web pages using React components use to declare each part of the site. For example, a navigation bar can be a component or an article on a web page can be a component. In turn, the article c component could consist of a comment component or a text component.

Components allow you to develop user interfaces that are easier to maintain and load quickly. Here are the main topics you should master when it comes to reacting components:

rendering lists

Lists are an important part of any site Web. Building a list in React is a great way to familiarize yourself with the basics of coding in React. As you get to know React, you should take the time to learn how to display lists of data on a web page.

State and prop management

State refers to how each object appears on a web page. Each component in a React application can have its own state, which is part of an object called ce.

Props, on the other hand, are used for sharing code between components. To work with React, you need to have a good understanding of both states and props. Here are the main topics you need to know:


Redux is a JavaScript library that makes it easy to manage the "state‚" of your application. Think about state in terms of what you’ve learned about components at this point.

The state of a component is like props that are passed to a component, like a simple JavaScript object. This object contains information that affects how a component is rendered.

Is -what ? this confused you a different way of looking Redux is that it helps you . manage data and see how you react to user actions Redux makes easier the management of the State; however, there a bit of a learning curve when starting up.

Next steps

We’ve only scratched the surface of React for JS concepts. Because the library is so popular, frequent updates are available. These updates continue to add even more features to make using React a more enjoyable experience.

The topics we covered above will give you an idea of ‚Äã‚ÄãReact’s basic capabilities. Once you have mastered these topics, you can continue to explore more advanced concepts of the React ecosystem:

, there is a lot you can learn once you master the basics! When you know the basics, these arguments come naturally to you. They are all based on the same fundamental principles used to create REACT library.
