i want split string first occurrence of 'dot' right left match.

//if have input string follows        var string = "hi.how.you" ;  //i need output following      output="you";

you can split dot , use pop() last element of resulting array:

var string = "hi.how.you" ; var last = string.split('.').pop() //=>
