How to split array into N subarrays in TypeScript

Answer 1

function splitArray(array : any, N : number) : any {
    let subarrays = [];
    
    for (let i = N; i > 0; i--) {
        subarrays.push(array.splice(0, Math.ceil(array.length / i)));
    }
    
    return subarrays;
}

const array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14];

const N = 4;

const subarrays = splitArray(array, N);

console.log(subarrays);

  
  
  
  
/*
run:
  
[[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11], [12, 13, 14]]
  
*/
