That was quick - Thanks , I prefer the one-liner ;-)

Keep in mind that this allocates a new array every time

Else you modify array p[] , or am I missing something here?

Yes, foreach, for loop modifies the array in place (ok, you can create a new array, but usually you don't). Just console.log out after each call to compare the different ways.
