+Chunks the provided array into the given number of arguments. Can be used with strings too using `Strig.protoype.split()` function.
+
+``` js
+const chunksArray = (arr,num) => {
+  let array = []
+  arr.forEach((el,i) => {if (i <= arr.length - num) array.push(arr.slice(i,i+num))} )
+  return array.length ? array : [arr]
+}
+```
+
+```js
+chunksArray([1,2,3,4,5],2); //[[1,2],[2,3],[3,4],[4,5]]
+chunksArray([1,2,3,4,5],5); //[[1,2,3,4,5]]
+chunksArray([1,2,3,4,5],10); //[[1,2,3,4,5]]
