Why is my regex returning null?

Coding Help

I have this regex: /(\\(n|t)){3}/gi
It should match against "\n\t\tDarkOrchid\n\t\t":

But, it doesn’t. Any idea why? I have the global and case insensitive flags set up.

Ok, I found the error - \n and \t are newline and tab, and are legal regex characters.
