Debugging JavaScript

Debugging JavaScript can be challenging, but with the right tools and techniques, you can quickly identify and fix issues. In this post, we’ll cover the basics of debugging JavaScript.

Using the Browser’s Developer Tools

Modern browsers come with built-in developer tools that make debugging easier. Here’s how to use them:

• Open the Developer Tools (usually by pressing F12 or right-clicking and selecting “Inspect”).
• Use the Console to view error messages and log output.
• Set breakpoints in the Sources panel to pause execution and inspect variables.

Debugging Tips

Here are some tips for debugging JavaScript:

• Use console.log() to print variables and messages to the Console.
• Check for syntax errors and typos.
• Use the debugger statement to pause execution at a specific point.

Here’s an example of using console.log() for debugging:

var x = 10;
console.log("The value of x is: " + x);
