The Fisher-Yates is one great way to prevent getting the same number twice by shuffling the sequence. There are many methods to achieve unique values without repetition. The randomization is based on the algorithm xorshift128+, which is likely running on your browser. This means its randomization can be reproduced under certain circumstances. This algorithm is called a pseudo-random number generator (or PRNG). Math.random() returns a pseudo-random number. There are a couple I see come up often… Is Math.random() really random?
