How JavaScript Works?

JavaScript is a programming language that is commonly used to add interactive features to web pages. It runs on the client side, which means that it is executed by the web browser on the user’s computer rather than on a server.

Here’s a high-level overview of how JavaScript works:

• A web page is loaded in a web browser and the HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) code is rendered to create the layout and style of the page.

• The web browser then looks for any JavaScript code that is included in the page. This code is usually included in one or more script elements in the HTML file.

• The JavaScript code is executed by the web browser. It can manipulate the HTML and CSS on the page, respond to user events such as clicks and form submissions, and make requests to servers (using technologies such as XMLHttpRequest or fetch).

• As the JavaScript code is executed, it can modify the content and appearance of the web page in real-time, making the page dynamic and interactive.

I hope this helps! Let me know if you have any other questions.

Thanks
