What is a digital root? According to wikipedia:

The digital root (also repeated digital sum) of a natural number in a given number base is the (single digit) value obtained by an iterative process of summing digits, on each iteration using the result from the previous iteration to compute a digit sum. The process continues until a single-digit number is reached.

With this package, simply call the digitalRoot function and pass a postive integer as an argument.

Examples:

digitalRoot(123);
// 1 + 2 + 3 = 6
// return 6

digitalRoot(8818);
// 8 + 8 + 1 + 8 = 25
// 2 + 5 = 7
// return 7

Enjoy!
