Your code had a syntax error, it is like this that ` \ ` is an escape character, where your code escaped the " character, which ment, you never really closed the string. By writing ` \\ ` you are actually looking for ` \ ` ;) (also in the comments it seems) — Icepickle

I think you just need to write double backslash for right split, because backslash is a special char.

var y = x.split("\\")[0];
