You will have to define your own function to get the same functionality. Try this:

function arrayKeys(input) {
    var output = new Array();
    var counter = 0;
    for (i in input) {
        output[counter++] = i;
    } 
    return output; 
}

arrayKeys({"one":1, "two":2, "three":3}); // returns ["one","two","three"]
