Effect.Effect<boolean, never, never>Generates a random boolean value.
When to use
Use to make a pseudo-random true-or-false choice.
Example (Generating a random boolean)
import { Effect, Random } from "effect"
const program = Effect.gen(function*() {
const value = yield* Random.nextBoolean
console.log("Random boolean:", value)
})Random Number Generators
