The Office IV - Find a Meeting Room ^{7 Kyu}

^{LINK TO THE KATA - FUNDAMENTALS ARRAYS}

Description

Your job at E-Corp is both boring and difficult. It isn't made any easier by the fact that everyone constantly wants to have a meeting with you, and that the meeting rooms are always taken!

In this kata, you will be given an array. Each value represents a meeting room. Your job? Find the first empty one and return its index (N.B. There may be more than one empty room in some test cases).

'X' --> busy
'O' --> empty

If all rooms are busy, return "None available!"

Solution

const meeting = x => (x.indexOf('O') < 0 ? 'None available!' : x.indexOf('O'))
