How do I debug JavaScript code effectively?

I'm having trouble with a JavaScript function that's not returning the expected result. How can I debug it?

First, try using console.log() to print out the values of variables at different points in your function. This can help you see where things might be going wrong.

I've added some console logs, but I'm still confused about the output. What should I look for?

Check if the values being logged are what you expect. Also, ensure that your function is being called correctly and that there are no syntax errors.

What if I still can't find the issue? Are there any tools that can help?

Yes! You can use browser developer tools, like the debugger in Chrome, which allows you to set breakpoints and step through your code.
