Are you a front-end developer and want to learn how to master React? Firstly, make peace with the fact that mastering these key five fundamentals of React will help you to become a React Swami.

We understand that as a front-end developer you desire to take your React.js knowledge to a top-level. Well, the good news is that this guide will pretty much pave the way for you. Learn everything you need to know on how to master React as your problems boil down to one thing – fundamentals of React.

Let’s get started.

An Eagle’s Eye Overview

One of the core unit of being of React are its ‘components’. In fact, you can even say that each application built in React will be made up of these five ingredients.

As React is believed as one of the superlative JavaScript libraries for constructing striking user interfaces; these five elements make the effort of constructing UIs much easier. The concept is pretty much simple; you can work on these components independently and join them all in a parent component which will be your ultimate UI.

Given below are the core five fundamentals of React to experience the big difference it makes: The five components of React are:

  1. Components
  2. JSX
  3. Props & State
  4. The Component API
  5. Component Types

1) Understanding React Components

React component lifecycle is distributed into three parts: Mounting, Updating, and Unmounting. Each component shadows a cycle when developing in React, from when it’s shaped and mounted to when it is unmounted and wiped out.

Mounting – putting elements into DOM (Document Object Model). DOM defines a logical structure of documents; react coders can form and build documents, steer their structure, can add, adjust, or erase elements and content.

Updating – the next phase is when a component accepts new props or a new state, it should update. ‘Props’ is a specific keyword in React defined for ‘properties’ means ‘passing data from one component to another.’ ‘State’ is where you ‘store property values that fit the component.’

Unmounting – it is the third phase where elements are removed from the DOM; depends if React wants to call this function.

2) Introducing JSX

JSX stands for JavaScript XML. It permits developers to write HTML in React and place it into DOM with ease. See the demonstration below where it shows how JSX allows you to code HTML directly within the JavaScript code.


const myelement = <h1>I Love JSX!</h1>;
ReactDOM.render(myelement, document.getElementById('root'));


const myelement = React.createElement('h1', {}, 'I do not use JSX!');
ReactDOM.render(myelement, document.getElementById('root'));

3) How to master react: Learn what is ‘Props and State’

‘Props’ like explained above is a shortcut to properties that is a function called to pass data between components. See below how you can pass data with props:

class ParentComponent extends Component {    
    render() {    
        return (        
            <ChildComponent name="First Child" />    
const ChildComponent = (props) => {    
    return <p>{props.name}</p>; 

Another built-in object in React is named ‘State’ that lets components to make and handle their own data. An important thing to comprehend is that you can not use ‘state’ to pass data between components but to manage internally. See below how it is achieved:

class Test extends React.Component {    
    constructor() {    
        this.state = {      
            id: 1,      
            name: "test"    
    render() {    
        return (      

4) The Component React API

React’s component API is a powerful API to make the code entirely reusable in the application. Some components being used comprises of the following:

  1. Render
  2. SetState
  3. Constructor

Render and setState are a part of component API methods as a small set. There is another one called Constructor that is quite useful and used to initialize state and bind approaches.
