Learn JavaScript

JavaScript is a versatile programming language primarily used for creating interactive effects within web browsers. Originally developed by Brendan Eich in 1995, it quickly became a cornerstone of web development due to its ability to dynamically modify webpage content, respond to user actions, and communicate with servers to fetch and send data without needing to reload the entire page. JavaScript is essential for creating modern web applications, ranging from simple features like form validation and animations to complex functionalities like interactive maps, real-time updates, and dynamic content loading. It's also commonly used in server-side development (Node.js) and for building mobile and desktop applications (through frameworks like React Native and Electron). With JavaScript, developers can manipulate HTML and CSS, handle events triggered by user actions (such as clicks, keyboard input, or mouse movements), perform calculations, manage data, and much more. It's supported by all major web browsers and has a vast ecosystem of libraries and frameworks, making it one of the most widely used programming languages in the world.

Key features of JavaScript:
  • Client-Side Language: JavaScript is executed in the web browser, when page is loaded JavaScript is executed to make the page dynamic.
  • Dynamic and Loosely Typed: In JavaScript variables are not bound to specific type and can change their type during execution.
  • Event-Driven Programming: Event listeners trigger functions on events like user clicks, key presses, page loads, etc.
  • First-Class Functions: Allows functions to be assigned to variables, passed as arguments, or returned from other functions.
  • Object-Oriented but Prototype-Based: Instead of using classical inheritance like Java, JavaScript uses prototype-based inheritance.
  • Asynchronous Programming with Callbacks, Promises, and Async/Await: JavaScript can handle various asynchronous operations .
