This is recopied from the pink section on the previous page. This did not make any sense to me whatsoever. No matter how I looked at it, I just couldn't get it...
If the separator -- content in the "( )" part -- is omitted, the returned array will contain the whole string in index [0]. If the separator is "", the returned array will be an array of single characters:
var txt = "Hello"; <== String
txt.split( ); <== Split in characters: This returns "Hello" horizontally
txt.split(""); <== Split in characters: This returns "Hello" vertically, when used as shown below:
