A codebase has a time dimension, and utilizing this effectively is critical.

Not sure when a bug was introduced? Write a test then bisect (if you can't automatically bisect frontend code you have other problems, but manual bisects work in a pinch).

Not sure why something was written the way it was? Hey sometimes this stuff just evolves naturally, try looking back through blame history to see how different commits effected the code.

Not sure what needs touching to add a new feature? Try seeing if you can find a similar feature that someone else wrote in the past.
