Problem
Let's say that I have an Javascript array looking as following:
What approach would be appropriate to chunk (split) the array into many smaller arrays with, lets say, 10 elements at its most?
["Element 1","Element 2","Element 3",...]; // with close to a hundred elements.What approach would be appropriate to chunk (split) the array into many smaller arrays with, lets say, 10 elements at its most?
Solution
The
The last
Note that a
array.slice() method can extract a slice from the beginning, middle, or end of an array for whatever purposes you require, without changing the original array.const chunkSize = 10;
for (let i = 0; i < array.length; i += chunkSize) {
const chunk = array.slice(i, i + chunkSize);
// do whatever
}The last
chunk may be smaller than chunkSize. For example when given an array of 12 elements the first chunk will have 10 elements, the second chunk only has 2.Note that a
chunkSize of 0 will cause an infinite loop.Code Snippets
const chunkSize = 10;
for (let i = 0; i < array.length; i += chunkSize) {
const chunk = array.slice(i, i + chunkSize);
// do whatever
