how to map an array with uppercase function in javascript?

Question

I\'m interested if there is any function like array_map or array_walk from php.

Don\'t need an for that travels all the array. I can do that for myself.

Answer 1

And here is the one-liner without creating a loop or a function that is ES3 compatible It's alos faster since you only call toUpperCase once

// watch out for strings with comma (eg: ["hi, max"]) then use custom join/split()
// or just use something safer such as Array.map()
var uppercaseArray = array.toString().toUpperCase().split(",");
var uppercaseArray = array.join(0).toUpperCase().split(0);
var uppercaseArray = (array+"").toUpperCase().split(",");
