Function numericSort

src/numeric_sort.js:18–28

* Sort an array of numbers by their numeric value, ensuring that the * array is not changed in place. * * This is necessary because the default behavior of .sort * in JavaScript is to sort arrays as string values * * [1, 10, 12, 102, 20].sort() * // output * [1, 10, 102, 12, 20]

(x)

 * numericSort([3, 2, 1]) // => [1, 2, 3]
