Question

How to split an array into evenly sized chunks in JavaScript

Answer 1

const split = (arr, chunk) => {
    const result = [];
    const size = arr.length;
    
    for (let i = 0; i < size; i += chunk) {
        result.push(arr.slice(i, i + chunk));
    }
    
    return result;
};

const arr = Array.from({ length: 31 }, (_, i) => i);

console.log(split(arr, 4));
