Monkeys eat bananas but break into several sections to eat Oh!

Divides an array of arr into a number of array blocks, as specified by the size of the arrays.

For example: Chunk ([1,2,3,4],2) =[[1,2],[3,4]];

Chunk ([1,2,3,4,5],2) =[[1,2],[3,4],[5]];

Results:

Chunk (["A", "B", "C", "D"], 2) should return [["A", "B"], ["C", "D"]].
Chunk ([0, 1, 2, 3, 4, 5], 3) should return [[0, 1, 2], [3, 4, 5]].
Chunk ([0, 1, 2, 3, 4, 5], 2) should return [[0, 1], [2, 3], [4, 5]].
Chunk ([0, 1, 2, 3, 4, 5], 4) should return [[0, 1, 2, 3], [4, 5]].
Chunk ([0, 1, 2, 3, 4, 5, 6], 3) should return [[0, 1, 2], [3, 4, 5], [6]].
Chunk ([0, 1, 2, 3, 4, 5, 6, 7, 8], 4) should return [[0, 1, 2, 3], [4, 5, 6, 7], [8]].

Code:

Method 1:

1 functionChunk (arr, size) {2   //Break it up3   vartemp = [];4   varresult = [];5 6    for(varA = 0; A < Arr.length; a++) {7     if(A% size!== size-1)8 Temp.push (Arr[a]);9     Else {Ten Temp.push (Arr[a]); One Result.push (temp); Atemp = []; -     } -   } the  -   if(temp.length!== 0) - Result.push (temp); -   returnresult; +}

Method Two:

1 functionChunk (arr, size) {2   //Break it up3   //It ' s already broken:(4arr =Arr.slice ();5   varARR2 = [];6    for(vari = 0, len = arr.length; i < Len; i+=size) {7Arr2.push (Arr.slice (0, size));8arr =arr.slice (size);9   }Ten   returnarr2; One}

Method Three:

1 functionChunk (arr, size) {2   //Break it up.3   varNEWARR = [];4   vari = 0;5 6    while(I <arr.length) {7Newarr.push (Arr.slice (i, i+size));8i + =size;9   }Ten   returnNEWARR; One } AChunk (["A", "B", "C", "D"], 2);

Method Four:

1 functionChunk (arr, size) {2   //Break it up3   varNewarr=[];4   5    for(vari=0;i<arr.length;i+=size) {6Newarr.push (Arr.slice (i,i+size));7   }8   returnNewarr;9 }Ten  OneChunk (["A", "B", "C", "D"], 2);
