What?:

It's a git pre-commit script that checks your Javascript code for errors before every commit, if it finds any issues it simply aborts the commit. Sgt-Donowitz helps you set this up in less than a minute.

Why?:

Because it's easier to maintain good code when you are forced to

How?:

from the root of your project run:

curl -s jt.io/lint | sh

Where?

Mac OS X / Unix only

What if?

If for some reason you must commit a JS file without validating/linting it you can always run a commit with the "no-verify" flag: i.e. git commit --no-verify .

However, when doing this remember that there are no flags to remove bad Karma.
