divide an array into groups of 2 code example

Example: react split array into chunks

const chunkSize = 10;
const arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17];
const groups = arr.map((e, i) => { 
     return i % chunkSize === 0 ? arr.slice(i, i + chunkSize) : null; 
}).filter(e => { return e; });
console.log({arr, groups})
