Create an array with n elements in JS

Create an array with n elements in JS.

javascript


[...Array(n).keys()]

Using spread operator

javascript


Array.from(Array(n).keys())

ES6

javascript


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

Create an array with n elements filled with zeros in JS

javascript


Array(n).fill(0)
// [0, 0, 0, 0]

Sometimes, I need to create an array with n elements but keep forgetting how to do that in JS, so this is to for references only.

Thanks for reading.
