问题
Chrome sources debugging has buttons for step over, step into, and step out. There is no stepping backwards in time to see what were the previous functions.
回答1:
You can sort of go backwards if you click through in the "Call Stack" on the right side to see the parent functions.
回答2:
As I said on this answer, you can step back by placing a new breakpoint and restarting the actual function. Hope this makes the trick.
回答3:
One quick workaround I found out is to make a small change to the source file any change is fine (space, comment, whatever) while you are in the middle of the breakpoint then press Ctrl+s (save the file) and it will jump back to the first break point in that source. Then you can check your changes (F10 'step-in') then make another change if needed, Save it and it will restart. This is the fastest approach I have so far.

This is what I was looking for and found this link first. It is a more advanced version of the question I suppose..
The correct keyword to help search this is "Time Travel Debugging"
First noted here in this version of nodejs called, "Node-ChakraCore".
