arrays - JavaScript split String with white space

Question

I would like to split a String but I would like to keep white space like:

var str = "my car is red";

var stringArray [];

stringArray [0] = "my";
stringArray [1] = " ";
stringArray [2] = "car";
stringArray [3] = " ";
stringArray [4] = "is";
stringArray [5] = " ";
stringArray [6] = "red";

How I can proceed to do that?

Thanks !

Using regex:

var str   = "my car is red";
var stringArray = str.split(/(s+)/);

console.log(stringArray); // ["my", " ", "car", " ", "is", " ", "red"] 

s matches any character that is a whitespace, adding the plus makes it greedy, matching a group starting with characters and ending with whitespace, and the next group starts when there is a character after the whitespace etc.
