Really like that function. $matches = array('12', 'watt'); list($value, $unit) = $matches; Is there a Javascript equivalent of that? Nicolás There is, but in "new" versions of Javascript: Destructuring assignment - Javascript 1.7 . It's probably only supported in Mozilla-based browsers, and maybe in Rhino. var a = 1; var b = 3; [a, b] = [b, a]; EDIT: actually it wouldn't surprise me if the V8 Javascript library (and thus Chrome) supports this. But don't count on it either :) try this: matches = ['12', 'watt']; [value, unit] = matches; ES6 does support this directly now via array destructuring

Is there a way in JavaScript to compare values from one array and see if it is in another array? Similar to PHP's in_array function? Paolo Bergantino No, it doesn't have one. For this reason most popular libraries come with one in their utility packages. Check out jQuery's inArray and Prototype's Array.indexOf for examples. jQuery's implementation of it is as simple as you might expect: function inArray(needle, haystack) { var length = haystack.length; for(var i = 0; i < length; i++) { if(haystack[i] == needle) return true; } return false; } If you are dealing with a sane amount of array
