FAQ

    What is JavaScript?
  • JavaScript is a versatile, high-level programming language primarily used for client-side web development. It allows developers to create dynamic, interactive web pages and applications.
    • How is JavaScript different from Java?
  • Despite the similar names, JavaScript and Java are distinct languages. JavaScript is primarily used for web development, while Java is a general-purpose language used for various applications, including Android development.
    • What are some popular JavaScript frameworks?
  • Popular JavaScript frameworks include React, Angular, Vue.js for frontend development, and Node.js with Express for backend development.
    • Can JavaScript be used for server-side programming?
  • Yes, with Node.js, JavaScript can be used for server-side programming, allowing developers to create full-stack applications using a single language.
    • What are the main features of ECMAScript 6 (ES6)?
  • ES6 introduced features like arrow functions, classes, template literals, destructuring, and the let and const keywords for variable declarations.
    • How does JavaScript handle asynchronous operations?
  • JavaScript uses callbacks, promises, and async/await syntax to handle asynchronous operations, allowing non-blocking execution of code.
    • What is the DOM and how does JavaScript interact with it?
  • The Document Object Model (DOM) is a programming interface for HTML documents. JavaScript can manipulate the DOM to dynamically change the content and structure of web pages.
    • How can I improve the performance of my JavaScript code?
  • Optimize performance by minimizing DOM manipulation, using efficient data structures, leveraging browser caching, and employing code splitting techniques.
    • What are closures in JavaScript?
