Git is a distributed version control system that keeps track of changes to code through snapshots of files and directories. It allows developers to work independently and merge changes together easily. Some key advantages of Git include its small size, ability to easily merge and branch code, and use of hooks for things like validating code commits.

22. Hooks

23. client side hooks
• pre-commit
• prepare commit
• commit message
• post commit
• pre rebase
• post checkout
• post merge

24. server side hooks
• pre-receive
• post-receive
• update (like pre-receive but per branch)

25. pre-commit jslint
for js in $(git diff-index --name-only --cached HEAD -- | grep '.js$'); do
if jslint.sh $js 2>&1 | grep 'Lint at line' ; then
echo $js
exit 1
else
echo "js files validated"
exit 0
fi
done
