Blame & Diff to Find Who Broke What

Git & GitHub

Technical Specification

Use git blame to see who last changed each line in a file, and git diff to compare versions.

Input/Output Samples

Input:git blame src/index.js

Output:commit hash + author + line

Optimal Logic Path

git blame src/index.js
git diff HEAD~1 HEAD src/index.js

Architectural Deep-Dive

Blame helps track who changed a line; diff shows what exactly changed between commits.
