What is git stash, and when would you use it? Follow:

Short answer: git stash temporarily saves your uncommitted changes so you can work on something else without committing unfinished work. Example: You’re fixing a login bug but suddenly need to switch branches to fix a production issue. Instead of committing half-done code, you run: git stash git checkout main Later, you can come back and reapply your stashed work.

Real-world example (ShopNest)

ShopNest’s team uses GitHub PRs with reviews and CI checks so broken builds never reach production unnoticed.
