Problem To Solve

Write best practice code in JS or Ruby (depending on the job you are looking for) to calculate the check digit of an ISBN13 barcode

The algorithm is:

Take each digit, from left to right and multiply them alternatively by 1 and 3

Sum those numbers

Take mod 10 of the summed figure

Subtract 10 and if the end number is 10, make it 0

Example for 978014300723:

(9×1) + (7×3) + (8×1) + (0×3) + (1×1) + (4×3) + (3×1) + (0×3) + (0×1) + (7×3) + (2×1) + (3×3)

86

86 mod 10 = 6

10 – 6 = 4

Therefore the complete ISBN is: 9780143007234
