Complete React JS Course 2026 : React JS For Beginners

Explore how ES6 classes use a constructor to initialize new objects created with the new keyword, with the class acting as a blueprint for shared properties and methods.

This lecture explains how let and const behave, with examples of reassigning values, mutable vs immutable, and block scope rules in ES6.

Explore es6 arrow functions: declare add with parameters a and b, compute a plus b, use implicit return, and note they lack an arguments object.

Explore ES6 array methods such as forEach, map, filter, and find on the fruits array, using arrow functions to iterate, multiply by ten, and filter even numbers.

Explore ES6 destructuring by unpacking values from arrays and objects, assigning them to variables, skipping elements, providing default values, and handling nested object properties.

Discover the ES6 spread operator to expand arrays and objects, copy arrays with three dots, and easily merge multiple arrays into a single result.

Explore how the ES6 spread operator copies a cricketer object with three dots and merges cricketer one and cricketer two into a single object.

Master the ES6 rest operator for arrays and objects by using three dots to collect remaining elements or properties during destructuring, creating a rest array or a details object.

Render lists in React by mapping over arrays and rendering each item with a unique key. See how map accesses each object and why unique keys ensure efficient updates.

Learn to build a simple React form with username and email, use useState to track input, prevent default submission, and display the entered data in an alert using control components.

Explore how the useState hook manages real-time user input by binding an input field to state and displaying the current value as you type.

Learn how the useEffect hook replicates lifecycle methods like mount, update, and unmount using a counter example. With an empty dependency array, it runs once after initial render.

Apply the useEffect hook to monitor count changes and log updates to the console, using a dependency array to run the effect only when count changes, illustrating component updates.

Use the useEffect hook to clean up resources on unmount with a cleanup function and an empty dependency array. Log mount and unmount events and observe the effect run once.

Learn to set up routing in a React app using React Router Dom, wrap components with browser router, define routes for home, about, and contact, and enable navigation links.

Install the React Router DOM package to enable browser routing and render home, about, and contact components through routes. Use link to navigate without refreshing the page.

Explore dynamic routing in React by using the useParams hook to extract a name parameter from the URL and render content on the about page, with Link components for navigation.

Build your React project with npm run build to create a production build, then deploy to Netlify via manual upload or GitHub integration.
