So I've done some development using the groovy language recently and wondered if javascript or jquery has something similar (I'll just use pseudo code to illustrate my point faster).

Say I have a function that accepts an array of strings, but the array I have contains integers:

myFunction([1, 2, 3, 4])

Lets say there was a function called toString in the library that converted objects to strings. If I tried just doing [1, 2, 3, 4].toString() it would just convert the array object into a string ('[1, 2, 3, 4]')

What I want is for the toString to act on the items inside the array and not on the array itself. In groovy I can access the individual items with an astrix:

[1, 2, 3, 4]*.toString() 

This is like doing an each and calling toString() on each item, but does it in one line. 

Just wondering if a shorthand like this exists in javascript/jquery?

Thanks,
