JavaScript is a programming language that enables you to create dynamic web content. For example, you can create drop-down menus, form validation, and responsive layouts. This tutorial covers the basics of JavaScript so that you can get started quickly.

JavaScript is a text-based programming language. That means that instead of writing code in binary (1s and 0s), you write code in words and sentences. This makes it much easier for humans to read and write code.

JavaScript is a case-sensitive language. That means that if you write a variable name in all lowercase letters, you must always write it in all lowercase letters. If you write a variable name in all uppercase letters, you must always write it in all uppercase letters.

JavaScript is an interpreted language. That means that when you write code, you don't have to worry about compiling it. The browser interprets your code for you.

JavaScript is a client-side scripting language. That means that the code is executed on your computer, not on the server. This makes JavaScript code very fast.

JavaScript is a object-oriented programming language. That means that you can create objects and methods to make your code more organized and efficient.

Now that you know the basics of JavaScript, you're ready to start coding!
