Function: shuffled()
ts
function shuffled<T>(items, pick?): T[];Defined in: @lelantos-org/sdk/dist/core/random.d.ts:47
A uniformly random permutation of items, as a new array.
Fisher–Yates, downwards, so every one of the n! orderings is equally likely — given an unbiased pick, which is why the default is randomBelow and not a scaled float.
pick(k) must return a uniform integer in [0, k); injecting one is how a test pins a specific permutation.
