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.

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.
