How do I add values to an array in a loop?

Question

I am trying to create a new key-value or associative array "gradepoints" using two old arrays "grades" and "array". I tried with and without curly braces in the loop.

var gradepoints = [];
for(var i=0; i<array.length; i++) {
    gradepoints[i] = {array[i] : grades[array[i]] };
}

Take a look at http://stackoverflow.com/questions/6298169/how-to-create-a-map-object-in-a-javascript — Alexander Jardim, Mar 12 '14 at 09:47
@Royi grades is like {'a': 10, 'b: 9, 'c': 8} and array is like {a,b,c} — user2714639, Mar 12 '14 at 09:50
Thanks guys (specially Alexander), I just wanted to use an object not array. For anyone looking for a solution, use gradepoints.push — user2714639, Mar 12 '14 at 09:56

var gradepoints = {};
for(var i=0; i<array.length; i++) {
    gradepoints[array[i]] = grades[array[i]];
}
