Function to extract the part starting from a substring in Javascript?

Question

Lets say i have the following string:

var myString = "hello and welcome to my website";

Is there any function in Javascript to extract the part starting from a given substring?

For exemple:

var newString = extractString(myString, "welcome");

And newString will be "welcome to my website".

Here you go

> myString = "hello and welcome to my website"
"hello and welcome to my website"
> part = myString.substr(myString.indexOf("welcome"))
"welcome to my website"

Note that this assumes the substring to be there, if this might not be the case, add a check:

var i = myString.indexOf(search)
if(i >= 0)
   ...ok
