var last = names.split(/\s+/).pop(); // "Mark"

Explanation: .split splits a string on a given separator and returns an array. /\s+/ is a regular expression for "one or more whitespaces" (space, tab, newline, etc). .pop() grabs the last value from the array that .split returns.

Answer from Roatin Marth is correct, but in case if you need 4 times faster version (in IE) of same operation:

var last = names.substr(names.lastIndexOf(" "));

It is working without regular expressions and temp arrays - just with index operations of string.
