How to pad an array to a specified length with a given value in TypeScript

Answer 1

function arrayPad(arr: number[], size: number, value: number): number[] {
    let paddedArray: number[] = arr.slice();
    let originalSize: number = arr.length;

    // Pad the array with the given value
    if (size > originalSize) {
        paddedArray = paddedArray.concat(new Array(size - originalSize).fill(value));
    }

    return paddedArray;
}

let arr: number[] = [1, 2, 3];
let size: number = 6;
let value: number = 0;

let paddedArray: number[] = arrayPad(arr, size, value);

console.log(paddedArray);

 
 
/*
run:
       
[1, 2, 3, 0, 0, 0]
     
*/
