We want an array, but not just any old array, an array with contents!Write a function that produces an array with the numbers 0 to N-1 in it.For example, the following code will result in an array containing the numbers 0 to 4:arr(5) // => [0,1,2,3,4]
Example 1: es6 create array with increasing number
Array.from(Array(10).keys())
//=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]Example 2: list from 1 to 100 js
[...Array(100).keys()]
//=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
