/*
Given an index and an array, return the value of the array with the given index.

Examples
valueAt([1, 2, 3, 4, 5, 6], 10 / 2) ➞ 6

valueAt([1, 2, 3, 4, 5, 6], 8.0 / 2) ➞ 5

valueAt([1, 2, 3, 4], 6.535355314 / 2) ➞ 4
If the index is an invalid one, give an appropriate error message, instead of printing “undefined”
