Let’s say I have test_23 and I want to remove test_.
How do I do that?
The prefix before _ can change.

My favourite way of doing this is "splitting and popping":
var str = "test_23";
alert(str.split("_").pop());
// -> 23
var str2 = "adifferenttest_153";
alert(str2.split("_").pop());
// -> 153
split() splits a string into an array of strings using a specified separator string. pop() removes the last element from an array and returns that element.
