Generating an array of integers in TypeScript

Question

Is there a simple way in TypeScript to generate an array of the first 10 integer numbers?

Such as I would do with Matlab with x = 1:10.

There is no built in syntax but you can easily build a helper function that takes `from` and `to` and returns array between them. — VLAZ, Feb 21 '20 at 16:24

You can use Array.from with a map function where you can use index inside map function o generate the number.

console.log(
  Array.from({ length: 10 }, (_, i) => i + 1)
)

You can do it using Array.prototype.fill and Array.prototype.map

let arr = Array(10).fill(0);
arr = arr.map((val, index) => index + 1);
console.log(arr);
