How do I debug JavaScript functions effectively?

I'm having trouble with a JavaScript function that's not returning the expected result. What should I do?

First, check for any syntax errors in your function. You can use the browser's developer tools to see if there are any error messages.

I've checked for syntax errors, but the function still doesn't work. What next?

Try adding console.log statements inside your function to track the values of variables at different points in the execution.

That helped! I can see where the logic is going wrong. Any tips on fixing it?

Make sure to review the logic flow and conditions in your function. Sometimes, restructuring the code can help clarify the logic.
