The generator that this module uses internally. It can be re-seeded with the seed function.
Generates a random boolean.
Return a boolean based on a probability.
A number between 0 and 1 representing the likelihood that true will be returned. A probability of 0 will always return false and a probability of 1 will always return true.
Selects a random element from array.
Generates a random float between min (inclusive) and max (exlusive).
Generates a random integer between min (inclusive) and max (exlusive).
Selects a random element from items.
Generates the next random number. Comparable to Math.random.
A number between 0-1
Sets the seed for the internal random number generator.
Shuffles an array in place.
If you want to return a new array, use shuffled.
Creates a shuffled copy of an array.
If you want to shuffle the array in place, use shuffle.
Select a value from a list of weighted items. A higher weight means an item is more likely to be selected.
let item = RNG.weighted([
{ weight: 1, value: "foo" },
{ weight: 2, value: "bar" },
{ weight: 3, value: "baz" },
