How To JS Introduction

 JS Basics Introduction

JavaScript (JS) is a high-level programming language that is commonly used in web development to create interactive and dynamic websites. It is a client-side scripting language, which means that it runs on the client's web browser rather than on the server.

JS is often used to add interactivity to web pages, such as validating user input, animating page elements, and creating interactive forms. It can also be used to create more complex applications, such as web-based games or data visualization tools.

To use JS on a web page, you can include the JavaScript code in the HTML file using the <script> tag. JS can also be loaded from external files.

Here is an example of a simple JS program that displays an alert box when the user clicks a button:

Javascript Copy code;

<button onclick="alert('Hello World!')">Click Me</button>

JS has a number of built-in objects and functions that can be used to manipulate web page elements and data. For example, the document object can be used to access and modify the content of a web page, and the Math object provides a range of mathematical functions.

JS is a versatile and powerful programming language, but it can also be complex and difficult to master. However, there are many resources available for learning JS, including online tutorials, courses, and documentation.
