Overview
JavaScript is a versatile, multi-paradigm language that supports event-driven, functional, and imperative programming styles. It was originally designed to add interactivity to web pages but has since evolved into a powerful language used for both frontend and backend development.
Key Concepts
- Asynchronous Programming: Using callbacks, promises, and async/await to handle non-blocking operations.
- Prototypal Inheritance: A unique inheritance model where objects inherit directly from other objects.
- First-Class Functions: Functions are treated as variables, allowing them to be passed as arguments or returned from other functions.
Ecosystem
JavaScript has a massive ecosystem of libraries and frameworks, including React, Vue, Angular, and Node.js.
