Yeah I can see you are converting a char code into a string using fromCharCode and comparing it against a regex which is slower and I showed you a function that checks non-alpha variables using charcodes. BTW your isWhiteSpace function also calls to functions indexOf/fromCharcode when it doesn't need to and also indexOf starts at 0 so you have to check if it's greater than -1.
