random

const random: IO<number>

Added in v1.0.0 (constant)

Returns a random number between 0 (inclusive) and 1 (exclusive). This is a direct wrapper around JavaScript’s Math.random().

randomBool

const randomBool: IO<boolean>

Added in v1.0.0 (constant)

Returns a random boolean value with an equal chance of being true or false

randomInt

(low: number, high: number): IO<number>

Added in v1.0.0 (function)

Takes a range specified by low (the first argument) and high (the second), and returns a random integer uniformly distributed in the closed interval [low, high]. It is unspecified what happens if low > high, or if either of low or high is not an integer.

randomRange

(min: number, max: number): IO<number>

Added in v1.0.0 (function)

Returns a random number between a minimum value (inclusive) and a maximum value (exclusive). It is unspecified what happens if maximum < minimum.
