JS replace all the string before another specified character

I have the string 

var str = "A > B > C > D > E";

expected output:

E

Means i want to remove/replace all the string upto last > symbol, or before > symbol from last.

Javascript replace will do the trick, but i don't know how to write the pattern for this.

or can we do this by split method?

Goran's solution is correct and beautiful (because of the regex). However, here's an alternative using String's .split method:

var str = "A > B > C > D > E";
var letters = str.split(' > '); 
var output = letters[letters.length - 1];

Using regex :

var str = "A > B > C > D > E";
var re = str.replace(/.*> /,"");

# print "E"

You can do it even simpler than using split or replace. Locate the last separator, and take the part of the string after that:

str = str.substr(str.lastIndexOf(' > ') + 3);
