5 Debug tips required for JS debuggingI've been using the printf debugger, which is generally smooth, but sometimes you'll find that you need a better approach. Here are a few JavaScript tips that you'll find very useful.1. Debugger;As I've said before, you can add a sentence to the JavaScript code debugger; to manually create a breakpoint effect.Do you need a br
