Question

How to split an array into evenly sized chunks in TypeScript

Answer 1

const split = (arr: number[], chunk: number) => {
    const result: number[][] = [];
    const size: number = arr.length;
     
    for (let i: number = 0; i < size; i += chunk) {
        result.push(arr.slice(i, i + chunk));
    }
     
    return result;
};
 
const arr: number[] = Array.from({ length: 26 }, (_, i) => i);
 
console.log(split(arr, 4));



/*
run:  

[[0, 1, 2, 3], [4, 5, 6, 7], [8, 9, 10, 11], [12, 13, 14, 15], [16, 17, 18, 19], [20, 21, 22, 23], [24, 25]]
