Array map method


maybe it’s late but can’t seem to find an array map method (like the one in JavaScript) for transforming each of the elements in an array with a custom function. Would be something like:

~originalArray = [1, 2, 3];

~doublesArray ={
    num * 2

~doublesArray.postln; // [2, 4, 6]

I know that in this particular example I could just:

~originalArray * 2

but am asking for more advanced cases.
