How to get JS debugging messages

Copy linkTweet thisAlerts:
Mar 04.2010

hi, I’m finding that I’m making silly mistakes (like small syntax errors) in my JS/html which are sometimes hard to spot straight away. For example, when coding python on the web, I usually use try: except: and then use the error function to output what went wrong on the webpage.

What do you guys recommend for debugging JS? Does JS have something similar?

Thanks.

We actually deploy it in production, not just in development, and only show error and warning messages. Customer service found it useful when trouble shooting bugs that our customers report.
