What should I do to improve my source code reading skills?
What is the sequence of actions should be undertaken if I, i.e., read some ~10k js (or not js) source to grasp its inner workings?
The "purpose part" for me is not that "wrong", I should say - I am able to read the source and in the end do what I wanted to with the source code, but my experience is small and I cannot be sure I do it correctly. Like, I was trying to tweak some js library, I opened Chrome Dev Tools, inspected the element -> event listeners -> click -> aha, this function does this and I have to adjust it accordingly.
But what if that was a C source code? Or way code with way more complicated callback? I honestly don't know how to read stack, or how to use debugger js.
The only book I have found is "Code Reading: The Open Source Perspective", which seems to be shitty.
