Like everyone, you get bugs in your application code. You start debugging, but when you step through your code line-by-line, the debugger sometimes jumps into a source file that’s not your code like JQuery. I’m sure you’ve experienced the annoyance of stepping through the library code before getting back to your own application code.
This simplifies the process greatly. It’s something that I think all Js Developer should know.
How to Blackbox
There are essentially two ways as of 10/18/2015.
Open the DevTools Settings and under Sources click Manage framework blackboxing.
However, easiest way to is find the source file for libraries and mark them as Blackbox.
You can use the context menu when working in the Sources panel. When viewing a file you can right-click in the editor. And you can right-click on a file in the file navigator. From there choose Blackbox Script.
