Everything you need to know about debugging Angular applications

I have gone through the complete article to understand how to debug Angular applications, but I couldn’t get any constructive reply. Can anyone please help me and point me to one perfect article so that I can learn and understand how to debug Angular Applications!

Below is the issue I am facing:
My Angular App is running in the Chrome Browser.
I’ve opened Chrome Developer tools and then Sources tab. But, I could not see any JavaScript code to be able to debug the code.
Do I need to do anything to generate JavaScript code in this tab?
BTW, I am new to Angular.
I am new to this indepth.dev website and this is my first post.
