I would like a clean way to fill an array on creation with reference to the current cell being filled without using a for loop to do it.
Example:
var myValue = 10;
const myArray = makeArray(10, myValue * i);
with the result being [0,10,20,30,40,50,60,70,80,90]
Example:
var myValue = 10;
const myArray = makeArray(10, myValue * i);
with the result being [0,10,20,30,40,50,60,70,80,90]

If you need numbers that aren't linear, you can call mapArray on a linear range. e.g.
const myArray = mapArray(range(0, 10), function(i) { return cos(i * 30 * degree) });The non-linear case is probably slower than a simple for loop – but profiling would say for sure.
