Calculating prime factors of a given number recursively @ Software Craftsmanship Berlin Meetup (2019-03-25)
/**
* Calculates the prime factors for a given number.
* - Note: Currently the function will chrash with numbers greater than ~2000 because of the recursive nature.
* - This could potentially be optimized with e.g. proper tail calls
*
* @param {number} number - number used to calculate the prime factors
* @returns {array} primeFactors
