Create a new chunk if the previous value, i,e

Example_snippet/controller/utility/_split.js/ var i,j, temporary, chunk = 10. . .
var i, j, temporary, chunk = 10;
for (i = 0, j = array.length; i < j; i += chunk) {
   temporary = array.slice(i, i + chunk);
   // do whatever
}

Example_snippet/controller/utility/_split.js/ const chunk = (arr, size) => a. . .
const chunk = (arr, size) => arr.reduce((acc, e, i) => (i % size ? acc[acc.length - 1].push(e) : acc.push([e]), acc), []);

// Examples
chunk([1, 2, 3, 4, 5, 6, 7, 8], 3); // [[1, 2, 3], [4, 5, 6], [7, 8]]
chunk([1, 2, 3, 4, 5, 6, 7, 8], 4); // [[1, 2, 3, 4], [5, 6, 7, 8]]

Use Array,from() to create a new array, that fits the number of chunks that will be produced

Example_snippet/controller/utility/_split.js/ //#Source https://bit.ly/2neWf. . .
//#Source https://bit.ly/2neWfJ2 
const chunk = (arr, size) =>
   Array.from({
         length: Math.ceil(arr.length / size)
      }, (v, i) =>
      arr.slice(i * size, i * size + size)
   );
console.log(chunk([1, 2, 3, 4, 5], 2));
Step 2 continued with [[1,2],[3,4],[5]] . . .
[
   [1, 2],
   [3, 4],
   [5]
]

After the slicing is done, the original array remains unchanged, Modern browsers support this method

Example_snippet/controller/utility/_javascript.js/ let numbersArr = [1 ,2 ,3 ,4 ,. . .
let numbersArr = [1, 2, 3, 4, 5, 6, 7, 8];

console.log(numbersArr.slice(2, 5));
console.log("Original Array: ", numbersArr);
