How to merge two arrays into a sorted array in TypeScript

Answer 1

function merge(arr1: number[], arr2: number[]) {
    const compare = (i: number, j: number) => { return i - j; }
     
    const merged: number[] = arr1.concat(arr2).sort(compare);
    
    return merged;
}
  
const arr1: number[] = [1, 3, 18, 5, 9, 7];
const arr2: number[] = [2, 4, 6];
  
const merged: number[] = merge(arr1, arr2);
  
console.log(merged);
