JavaScript is a versatile, dynamically typed programming language that brings life to web pages by making them interactive. It is used for building interactive web applications and supports both client-side and server-side development.
- Dynamically typed: Variable types are determined at runtime.
- Single-threaded: Executes one task at a time (but supports asynchronous operations).
- Compiled and interpreted: Modern JavaScript engines combine compilation and interpretation for better performance.
