Here is my code: function flatten (arr) { arr2 = []; for (let i = 0; i < arr.length; i++) { arr2.concat(arr[i]); } } return arr2; But... it doesn't seem to be working! Fix my code so that it correctly flattens the array. Examples flatten ([[1, 2], [3, 4]]) [] // Expected: [1, 2, 3, 4] flatten([["a", "b"], ["c", "d"]]) → [] // Expected: ["a", "b", "c", "d"] - flatten ([[true, false], [false, false]]) → [] // Expected: [true, false, false, false]
