Let's say I want a variable to contain numbers from 1 to 100.
I could do it like this:

var numbers = [1,2,3,4,...,98,99,100]

But it would take a bunch of time to write all those numbers down.
Is there any way to set a range to that variable? Something like:

var numbers = [from 1, to 100]

This might sound like a really nooby question but haven't been able to figure it out myself. Thanks in advance.

In addition to this answer, here are some ways to do it:

for loop:

var numbers = []

for (var i = 1; i <= 100; i++) {

    numbers.push(i)

}

var numbers = Array(100).fill().map(function(v, i) { return i + 1; })

Or, if you are allowed to use arrow functions:

var numbers = Array(100).fill().map((v, i) => i + 1)

Or, if you are allowed to use the spread operator:

var numbers = [...Array(100)].map((v, i) => i + 1)

However, note that using the for loop is the fastest.
