Array of int - Javascript

Question

If I make this line in C\C++:

int myArray[10] = { 0 }; // all elements 0

I will have an array of ten zeros. How can I make in the same mode an array in Javascript, without for loop and push commands?

Answer 1

1. Create an array of 11 undefined elements
2. join them by using 0 as string
3. split the array by empty string
4. Use map to convert the strings to number

var myArray = new Array(11).join('0').split('').map(Number);

console.log(myArray);
document.write('<pre>' + JSON.stringify(myArray, 0, 2) + '</pre>');

Answer 2

Use this

Array(10).fill(0);
