getByIndex(index, array): any
Returns 1 item from array, accessed by its index.
So why use this instead of simply writing array[index]? This lets you use a
negative index, and will also trigger an error if the index doesn't exist in the array.
Examples
let arr = [1,2,3,4,5,6,7];
getByIndex(-1, arr); // --> 7
getByIndex(3, arr); // --> 4
getByIndex(-7, arr); // --> 1
getByIndex(-8, arr);
// Error: "The entered index is not valid. Whether positive or negative,
// it exceeds the index range of the array."Installation
