What is JavaScript used for?
JavaScript is used to create interactive websites, build web applications, develop servers with Node.js, and create browser-based games.
Is JavaScript suitable for absolute beginners?
Yes. Beginners can start with variables, functions, conditions, loops, and basic DOM manipulation before moving to advanced topics.
What should I learn first in JavaScript?
Start with syntax, data types, operators, functions, arrays, objects, and control flow. Then learn the DOM, events, and asynchronous programming.
