I created a javascript file in Plunker and I want to debug it. When I open 'Sources' panel, I don't see js file that I created. I only see plenty of Plunker js files. Please advice. Thanks
You have two main options to drill down to the source file that you created.
1. Use the pop-up window mode of the preview panel
By default, the previewer runs inside an <iframe> inside the plunker webapp. You can ask plunker to show the previewer in a separate window by clicking the blue expand icon in the top right of the preview window. If you open dev tools for the pop-up window, you will only see your source files.
2. Right click the preview and hit inspect element
Doing it this way will let you use the embedded, live preview and will give you a shortcut to drill down to the DOM associated with your code.
