Javascript features

JavaScript is a programming language that lets developers create interactive web pages. It is a high-level and interpreted programming language that is primarily used for building interactive and dynamic websites.

JavaScript is one of the most popular programming languages, which includes several features when it comes to web development. Some of its key features are lightweight, dynamic, functional, and interpreted.

Lightweight & Interpreted (JIT-Compiled): Executes directly in environments like browsers or Node.js without requiring prior manual compilation, utilizing Just-In-Time (JIT) compilers for fast runtime performance.

Dynamically Typed: Variable types are resolved at runtime rather than compile-time, meaning a single variable can hold different data types over its lifecycle without explicit type declarations.

Single-Threaded with Asynchronous Processing: Uses a single main call stack paired with an Event Loop (microtask and macrotask queues) to handle non-blocking asynchronous operations such as API requests, timers, and file I/O.
