how to generate a fibonacci sequence in javascript fibonacci counter in typescript

// declare the array starting with the first 2 values of the fibonacci sequence

    let fibonacci = [0,1];

    function listFibonacci(num) {

    // starting at array index 1, and push current index + previous index to the array

        for (let i = 1; i < num; i++) {
            fibonacci.push(fibonacci[i] + fibonacci[i - 1]);
        }
        console.log(fibonacci);
    }
    
    listFibonacci(10);
    'use strict';

let fibonacci: number[] = [0, 1];

function listFibonacci(num: number) {
  for (let i: number = 2; i < num; i++) {
    fibonacci[i] = fibonacci[i - 2] + fibonacci[i - 1];
  }
  return fibonacci;
}
console.log(listFibonacci(10));
