Unlike other full frameworks, ReactJS focuses exclusively on the view layer of applications. The core strength of ReactJS features in its component-based architecture, which permits developers to break down the UI into reusable pieces.<\/span><\/p>\n<h3><strong>Core Concepts of ReactJS<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Embarking on the journey in the field of developing in ReactJS, it would be highly relevant to understand a few concepts that form the base of ReactJS:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>JSX (JavaScript XML):<\/b><span style=\"font-weight: 400;\"> JSX is an extension syntax for JavaScript that looks like HTML. It enables the developer to write HTML-like structures in the same file as the JavaScript code, which makes it easy to render UI components.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Components:<\/b><span style=\"font-weight: 400;\"> React is all about components. Components are the building blocks of any React application. They can be functional-using functions to define them-or class-based-using ES6 classes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Props and State: <\/b><span style=\"font-weight: 400;\">Props is a shortened form of properties, which is the way data is passed from one component to another. While State is to manage data within a component. Both these mechanisms are important for managing your UI&#8217;s behaviour and how it updates.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Virtual DOM: <\/b><span style=\"font-weight: 400;\">It has a virtual DOM that is a copy of the real DOM, and because of it React can perform better than others. It only updates what&#8217;s changed in the UI, it doesn&#8217;t re-render everything on every update.<\/span><\/li>\n<\/ul>\n<h3><strong>Prerequisites for ReactJS Development<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Before diving deep into ReactJS development, a few foundational skills and tools with which you should be comfortable are listed below.<\/span><\/p>\n<p><strong>Basic Knowledge of HTML, CSS and JavaScript<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">React is built on top of plain web technologies: HTML, CSS, and JavaScript. You&#8217;ll need to master these first before diving into React. More precisely, you&#8217;ll want to familiarize yourself with modern JavaScript, more commonly known as ES6 features of JavaScript: arrow functions, destructuring, and classes.<\/span><\/p>\n<p><strong>Recommended Resources:<\/strong><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">MDN for the basics of JavaScript<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">JavaScript.info for advanced topics<\/span><\/li>\n<\/ul>\n<h4><strong>Setting Up a Development Environment<\/strong><\/h4>\n<p><span style=\"font-weight: 400;\">First of all, to start working with React, you would like to set up a development environment. That said, you should have the following basic requirements set up, such as:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Node.js and npm<\/b><span style=\"font-weight: 400;\">: Node.js is used to build React projects, and all dependencies for such projects are managed via npm. You would install the required packages or dependencies through npm, and similarly for running the development server.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Text Editors: <\/b><span style=\"font-weight: 400;\">Some of the popular text editors-Visual Studio Code and Sublime Text-have helpful extensions and integrations for React development in editing\/writing code.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Browser Developer Tools:<\/b><span style=\"font-weight: 400;\"> As a React developer, one prefers debugging an application, inspecting it using Chrome or Firefox developer tools.<\/span><\/li>\n<\/ul>\n<h3><strong>Setting Up Your First ReactJS Project<\/strong><\/h3>\n<h4><strong>Using Create React App (CRA)<\/strong><\/h4>\n<p><span style=\"font-weight: 400;\">The easiest way to set up your first ReactJS development project is by using Create React App (CRA), a command-line tool that simplifies the process:<\/span><\/p>\n<p><b>Install Node.js and npm<\/b><span style=\"font-weight: 400;\"> if you haven&#8217;t already.<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">npm install -g create-react-app<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Create your React App<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\">npx create-react-app my-react-app<br \/>\n<\/span>cd my-react-app<br \/>\nnpm start<\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Once the app is created, you\u2019ll have a fully functional React project with a development server running. Visit <\/span><span style=\"font-weight: 400;\">http:\/\/localhost:3000<\/span><span style=\"font-weight: 400;\"> to view the app in your browser.<\/span><\/li>\n<\/ol>\n<h4><b>Understanding the Project Files<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">React projects have a basic folder structure that you&#8217;ll encounter:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>public folder:<\/b><span style=\"font-weight: 400;\"> Contains static files such as <\/span><span style=\"font-weight: 400;\">index.html<\/span><span style=\"font-weight: 400;\">.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>src folder:<\/b><span style=\"font-weight: 400;\"> This is where the main development happens. Files like <\/span><span style=\"font-weight: 400;\">App.js<\/span><span style=\"font-weight: 400;\"> and <\/span><span style=\"font-weight: 400;\">index.js<\/span><span style=\"font-weight: 400;\"> are essential, as they handle the primary component rendering.<\/span><\/li>\n<\/ul>\n<h3><b>Building Components in ReactJS<\/b><\/h3>\n<h4><b>Creating Your First Component<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">A React component is essentially a JavaScript function or class that returns JSX. Let\u2019s create a simple functional component:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">function Greeting() {<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0return &lt;h1&gt;Hello, React Developer!&lt;\/h1&gt;;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">}<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Functional components are easier to start with, but class components offer more advanced features like lifecycle methods.<\/span><\/p>\n<h4><b>Passing Data Between Components<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">React uses <\/span><b>Props<\/b><span style=\"font-weight: 400;\"> to pass data between components. For example, if you want a <\/span><span style=\"font-weight: 400;\">Greeting<\/span><span style=\"font-weight: 400;\"> component to accept a name prop:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">function Greeting(props) {<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u00a0\u00a0return &lt;h1&gt;Hello, {props.name}!&lt;\/h1&gt;;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">}<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can then pass the prop when rendering the component:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&lt;Greeting name=&#8221;XYZ&#8221; \/&gt;<\/span><\/p>\n<h4><b>Handling Events<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">React handles events just like normal HTML, but with slight changes. For example, the <\/span><span style=\"font-weight: 400;\">onClick<\/span><span style=\"font-weight: 400;\"> event:<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&lt;button onClick={() =&gt; alert(&#8216;Button Clicked!&#8217;)}&gt;Click Me&lt;\/button&gt;<\/span><\/p>\n<h3><b>Styling Your React Application<\/b><\/h3>\n<h4><b>CSS in ReactJS<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">Styling in React can be done through regular <\/span><b>CSS stylesheets<\/b><span style=\"font-weight: 400;\"> or <\/span><b>inline styles<\/b><span style=\"font-weight: 400;\">.
