What is squashing?

Squashing is a process in which we squeeze multiple commits into one pretending it is only a single commit.

Basically squashing commits means we are rewriting the history of commits to make them look like single commit.

Why squashing commits is necessary?

Hi! This question may have already been asked (and answered). Please consider referring to any of the following threads, and remember to use search next time. Thank you :)

Just out of curiosity, which is better for development, Windows or Mac? I personally use windows and haven't used a Mac? So just wanted your opinion ? https://www.facebook.com/groups/hackathonhackers/permalink/1058602237528594/

Why should one get a macbook pro? Haven't used one ever. https://www.facebook.com/groups/hackathonhackers/permalink/1057089381013213/

Alright, Time for a new laptop for College. Mac or PC? Going to college for CS. https://www.facebook.com/groups/hackathonhackers/permalink/1056270107761807/
