Given an array add all the number elements and return the binary equivalent of that sum; to make the code bullet proof anything else than a number should be addeded as 0 since it can’t be addeded.
If your language can handle float binaries assume the array won’t contain float or doubles.
arr2bin([1,2]) == ’11’
arr2bin([1,2,’a’]) == ’11’
arr2bin() == ‘0’
This is a modification on the Kata: Array2Binary addition hope you like it
(total, value) => (typeof value === ‘number’ ? total + value : total),
