Usage of the var myArray = Array(10).fill(0); and var myArray = new Array(10).fill(0); seemingly return the same result.

Are there any differences between these two expressions? When should you use the new keyword and when should you not?

    It's in the spec that the Array constructor must work that way. Not all constructors do however. Commented Nov 13, 2018 at 15:20
