/*Syntax explanation -----------------------------
Returns an array of strings seperated at every 
point where the 'separator' (string or regex) occurs. 
The 'limit' is an optional non-sub-zero integer. 
If provided, the string will split every time the 
separator occurs until the array 'limit' has been reached.
