Array with numbers 1-20

I'm brand new to javascript. I was working through a problem earlier where I needed an array that included the numbers 1 thru 20.

I did this with the following:

var numberArray = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20];

QUESTION:

I can't help but think that this is not efficient (and certainly not scalable). Is there a way to create an array that automatically populates with sequential values between 1 and 20, or 1 and 1000 for instance?

You could use a simple loop to do what you want;

var numberArray = [];



for(var i = 1; i <= 20; i++){

    numberArray.push(i);

}



console.log(numberArray);
