extension

Raw

gistfile1.js

	function extension(filename) {
	return filename.split('.').pop();
	}

If filename equals "txt" then the extension popped from the array is "txt".
A solution would be to implement your function as follow :

function extension(filename) {
    return filename.split(".").slice(1).pop() || "";
}
