Package: effect
Module: Predicate

Predicate.some

Takes an iterable of predicates and returns a new predicate. The new predicate returns true if at least one predicate in the collection returns true for a given value.

This is like Array.prototype.some but for a collection of predicates.

Example

import * as assert from "node:assert"
import { Predicate } from "effect"

const isNegative = (n: number) => n < 0
const isOdd = (n: number) => n % 2 !== 0

const isNegativeOrOdd = Predicate.some([isNegative, isOdd])

assert.strictEqual(isNegativeOrOdd(-2), true) // isNegative is true
assert.strictEqual(isNegativeOrOdd(3), true)  // isOdd is true
assert.strictEqual(isNegativeOrOdd(4), false) // both are false
