Whether you are a freelancer looking to expand your skill set or a budding full stack developer eager to delve into frontend and backend technologies, understanding JavaScript is essential. In this comprehensive guide, we will explore what JavaScript is, how it works, and its significance in the tech industry.

What is JavaScript?

JavaScript is a high-level, interpreted programming language that adds interactivity to web pages. It is widely used to create dynamic content, handle user input, and communicate with servers through APIs. JavaScript serves as the foundation for building interactive websites and web applications.

How Does JavaScript Work?

JavaScript code is typically embedded within HTML documents and executed by web browsers.
