How to expand and fill an array with a single element in typescript?

Question

In python, if I want to create an array like [1, 1, 1, 1, 1, 1, 1, 1, 1, 1] I only need to do [1] * 10

>>> [1] * 10
[1, 1, 1, 1, 1, 1, 1, 1, 1, 1]

Can I achieve the same in typescript?

const array = new Array(10).fill(1);

It actually originates from javascript, but of course, works on typescript too.

you can try out

Array.from({ length: 10}, () => 1) - with this you can provide function that can initialize your array with the function output , currently function returns 1 so it initialize array with 1.

or

new Array(10).fill(1); (Already as given in comment)
