How to ignore js files on a specific subfolder?

Question

I have the following structure

I want to tell .gitignore to ignore js, map file types.

I tried the following

# =========================
# Web essentials auto-generated files
# =========================
TypeScript.Content/Scripts/*.js
TypeScript.Content/Scripts/*.js.map

But when I change the js file (or 'create' it) it adds to the list of pending changes...

Is something wrong?

It seems that the .js and .map files that you wish git to ignore are already present in the index. You need to tell git to un-track those files:

git rm --cached TypeScriptTest.Content/Scripts/*.js
git rm --cached TypeScriptTest.Content/Scripts/*.js.map

Quote from GitHub help on Ignoring files:

Note that git will not ignore a file that was already tracked before a rule was added to this file to ignore it.
