JavaScript - Debugging

Debugging in JavaScript is the process of identifying and fixing errors in code. It involves using tools and techniques to isolate and resolve bugs, such as using console.log statements to print values, using the browser's developer tools to inspect elements and monitor network requests, and using breakpoints to pause code execution. Debugging is an important part of the software development process and helps to ensure that code is functioning as intended.

Here are various ways to debug your JavaScript:

Use a JavaScript Validator

One way to check your JavaScript code for strange bugs is to run it through a program that checks it to make sure it is valid and that it follows the official syntax rules of the language. These programs are called validating parsers or just validators for short, and often come with commercial HTML and JavaScript editors.

Add Debugging Code to Your Programs

You can use the alert() or document.write() methods in your program to debug your code.
