Tipps for JavaScript Code Navigation

Hi all,

I am an expierenced Java / C# / C++ Game & Backend Developer trying to learn something new (JavaScript - Node.Js).
I think I understand the language itself now, but I have a very very hard time to read and more specificly "Navigate" through JavaScript code as I am usually used to work with compiled datatypes...

For example if I go into the target code of reuqire('target') and want to see on how many places this module is used I can not find it with "Find Usage" :/
Most of the time I use "Find Usage"... in general... results in a list of more than 20 results where nothing seems to be the usage I care for...
So from my perspective it seems like the best "Find Usage" is to STRG + SHIFT + F and manually search for occurences?

Do you guys maybe have some JavaScript Code Navigation Tipps for me?

Best regards,
Tom
