JS

JavaScript is a high-level, dynamic, and interpreted programming language primarily used for creating interactive effects within web browsers. It was originally developed by Netscape to enable dynamic content on web pages.

Key features of JavaScript include:

  • Client-Side Scripting: JavaScript runs in the browser, enabling real-time interaction without needing to refresh the page.
  • Versatile: It can be used for both front-end (browser-side) and back-end (server-side) development, especially with frameworks like Node.js.
  • Event-driven: JavaScript allows for event handling, making web pages interactive and responsive to user actions.
  • Asynchronous Programming: JavaScript supports asynchronous operations, which is useful for tasks like fetching data from a server without interrupting the user interface.
  • Dynamic Typing: Variables in JavaScript do not require an explicit data type declaration, and the type can change at runtime.
  • JavaScript is widely used with frameworks and libraries like React, Angular, and Vue.js to build modern web applications.
