Script Preparation code:

var arr = [];

for (i = 0; i < 1000; i++) {
  arr[i] = i;
}

 
var arr = [];​for (i = 0; i < 1000; i++) {  arr[i] = i;}

Tests:

var [met, rest] = _.partition(arr, function(i) { return i % 2 === 0 });

 
var [met, rest] = _.partition(arr, function(i) { return i % 2 === 0 });

var [met, rest] = arr.reduce(function(res, i) { 
if (i % 2 === 0) { res[0].push(i) } else {res[1].push(i) }
return res


 }, [[], []])

 
var [met, rest] = arr.reduce(function(res, i) { if (i % 2 === 0) { res[0].push(i) } else {res[1].push(i) }return res​​ }, [[], []])
