You can use both javascript methods repeat() and split() together.

" ".repeat(10).split(" ")

This code will create an array that has 10 item and each item is empty string.

const items = " ".repeat(10).split(" ")

document.getElementById("context").innerHTML = items.map((item, index) => index)

console.log("items: ", items)
