About Random Number Generator
The numbers come from your browser's cryptographic random source rather than Math.random, and the mapping into your range rejects biased values, so every number in the range is equally likely. That matters for draws and giveaways, where a subtle bias would favor part of the range.
Turn duplicates off when you are drawing distinct things, such as raffle tickets or lottery numbers. Leave them on when each draw should be independent, like simulating dice rolls.
