0 to "zero"?

Question

Declare a function getSimpleNumberName.

/**
* @param {number} ??? - the number whose name should be returned (0-10)
* @returns {'zero'|'one'|'two'|'three'|'four'|'five'|'six'|'seven'|'eight'|'nine'|'ten'} the name of the given number
*/

actual = getSimpleNumberName(0);
expected = "zero";

Is there a way to convert the number 0 to the string "zero" quickly? Any help appreciated.

Answer 1

You can split a string "Zero,One,Two,Three,Four,..." using comma ',' then obtain an element from the resulting array using <n> as index.

Answer 2

I would suggest manually filling an array if you're bound to the range [0, 10]. Like this:

var nums = ["zero", "one", "two", ..., "nine", "ten"];

The answer for input n would then be nums[n].

Since arrays aren't actual arrays but rather objects that pretend to be arrays, accessing an index out of range would give you undefined in return, as would accessing a field that doesn't exist. But that shouldn't be a problem if you want your function to only behave correctly for a valid input.
