The survey State Of JavaScript Survey Results: Front-end Frameworks carried out confirmed React JS’s highest satisfaction.
Both developers and entrepreneurs agree that React JS is the future of oriented framework, and it’s very worth investing money and time to it.
Besides these 4 reasons pointed out, there are tons of other reasons why you should start learning React JS immediately, such as
React has been used extensively by Instagram, Netflix, Paypal, and Apple. Initially, Facebook started using React JS in 2011 for the first time, and others followed later
- It can be used to produce any type of web application, native mobile app, command-line interfaces and so much more.
- React is one of the most popular JavaScript frameworks and is fastening its leading point with its continual growth.
- It is capable of building any complex UI keeping state out of the DOM. React employs a Virtual DOM that makes sure of maximum efficiency by only re-rendering nodes whenever required.
- It’s much easier to learn! If you have good knowledge of JavaScript, you could learn React JS in a couple of days. Of course, it takes time to master it, but it wouldn’t take as much as any of its cousins.
Useful free resources to learn React JS
- Once you’re committed to start learning React JS, it comes to question where you can start learning this amazing framework.
- The chances are amazingly interesting as the best ones are completely free.
- That’s probably why React JS is one of the most loved frameworks of JavaScript.
- Let’s know some of the resources that will help you learn React JS faster.
The official React JS documentation
- It’s very, very thoroughly detailed. The official documentation will address each and every trivial detail, including all the essential ones. It starts from installation and gets you to a more advanced level of React JS.
Building React JS apps with Redux:
- Redux is a concept you’ll engage while using React JS.
- Starting with the most basic elements, Geary shows you how to use Redux as a stand-alone state container. It might look weird and complex at first, but the book will clear it out for you.
- Show you how React bindings for Redux allow you to separate stateless presentation components from components that are actually connected to React.
Top 5 Skills You Must Know Before You Learn ReactJS
Do you know enough javascript before jumping into React??
Do you know how to use the map() method to loop through an array in javascript or ReactJS??
If you are learning React and you get stuck on these kinds of above questions then definitely you are doing mistakes in your learning process. There is no doubt that ReactJS is the most popular library among frontend developers and its popularity is continuously increasing day by day. The website running on ReactJS looks beautiful and most of the beginners in development get attracted to ReactJs (developed by Facebook) as well but a common mistake that a lot of developers and experienced people make is jumping directly into ReactJS (or some other library and framework) without knowing the prerequisites. If you will directly go to the React you will face a lot of problems while learning this library and in interviews as well.
You will get stuck during your interview if you will be asked some questions related to ES6, JSX, Babel, Package manager, basic javascript or some other fundamental concepts. We are going to discuss some prerequisites and some basic concepts that you should know before you jump to the React. These basic concepts will also help you to pick up some other frameworks and libraries of javascript in the future.
1. HTML and CSS
- Every front end developer starts their journey with HTML and CSS. So before you start learning to react you should have good command on writing HTML and CSS. You should know how to write semantic HTML tags, how to write CSS selectors, how to use classes, how to implement a CSS reset, box model, how to reset to border-box, flexbox, how to write responsive web applications including media queries and how to build a frontend application using HTML and CSS.
2. JSX (Javascript XML) & Babel
- In React you will work with JSX that looks like HTML and you can consider it like HTML-flavored JavaScript. It is the easiest way to add HTML code inside javascript or you can say it is the extension of the Javascript language syntax. You should have a complete understanding of what is JSX before you start learning React.
3. Fundamentals of Javascript and ES6
- No matter what… you can’t get better at React if your javascript fundamental is not clear. During the interviews, it is one of the essential skills to learn before moving to react. Javascript is one of the most confusing languages for developers and it ignores small errors that can create a problem in your project if you won’t notice it earlier. So make sure that you first clear your basic concept about javascript and then you move to the advanced version or ECMAScript5 and ECMAScript6. Some of the topics are given below but make sure that you explore as much as you can and build some projects as well for in-depth knowledge in javascript.
- Remember that building the basic foundation of javascript will help you to learn any framework but if the concept won’t be clear you will get stuck in any javascript framework. Also, the interviewer will check your fundamentals in javascript first before moving to the React.
- Start with variables, number, boolean, string and make your concepts clear about other very basic fundamentals. Make some small app on that like a calculator to see how things work together.
- Learn about operators, conditionals, functions, loops, javascript keywords, array, objects and other fundamentals.
- Event handling, DOM manipulation and how ‘this’ keyword works totally different in javascript (which is confusing for most of the developers).
- Higher order function, callback function, arrow function, state (how state and setState() function works) scope, class & constructors, extends and inheritance, map, reduce, filter, promises, modules, closures, const, let (difference between var, let and const) and other features of ES5 and ES6.
4. Package Manager (Node + Npm)
- When you will be working with ReactJS you’ll have to install many, smaller software packages. Package in javascript contains all the files needed for a module and modules are the javascript libraries that can be included in the Node project. Packages contain two things…package.json files + js file. To install these packages you need a good installer that can help you to download and install software packages easily without worrying about the dependencies. Here NPM (Node package manager) plays a role and helps you to install and keep track of javascript software. You can use NodeJs or Yarn to manage these software packages. You can install NPM by installing Node.js. When you install Node.js, NPM will install automatically.
- So before moving to React, you should have a solid understanding NPM (Node package manager) registry and how to install packages using NPM. NPM registry keeps track of the file that has been submitted. Anybody can submit these files (packages or modules). In short NPM registry is the place where developers can go and get the software to build software.
- Let’s suppose a person has written some javascript file that is really useful. He/she thinks that the other people might use it so he/she pushes it to the NPM registry. Somebody else can get it from NPM web registry and download it for their own purpose. Learn about the NPM more from GeeksforGeeks.
5. Git and CLI (Command Line Interface)
- Git (version control) is another must-have skill a developer should have to store their project on GitHub, Bitbucket and GitLab (Code hosting platform). It helps developers to work and collaborate with each other and it allows them to track and host different versions of project files. You should have good knowledge that how Git and these code hosting platforms work. Developers use the command of Git to track the version of your files, so learn how to use all the commands such as push, pull, add, commit, etc. Also learn about merging, branching, handling merging conflicts, etc.
- Everything in React you will be doing with the help of CLI (Command-line interface). Installing packages, using NPM, creating a react app, running react application and a lot of things so you really need to make a habit of using CLI. Below is the example of running a react application using CLI.
