Package: effect
Module: Array

Array.every

Checks whether all elements satisfy the predicate. Supports refinements for type narrowing.

When to use

Use to check whether every array element satisfies a predicate, including refinement-based type narrowing.

Example (Testing all elements)

import { Array } from "effect"

console.log(Array.every([2, 4, 6], (x) => x % 2 === 0)) // true
console.log(Array.every([2, 3, 6], (x) => x % 2 === 0)) // false

• some — test if any element matches

Signature

declare const every: { <A, B extends A>(refinement: (a: NoInfer<A>, i: number) => a is B): (self: ReadonlyArray<A>) => self is ReadonlyArray<B>; <A>(predicate: (a: NoInfer<A>, i: number) => boolean): (self: ReadonlyArray<A>) => boolean; <A, B extends A>(self: ReadonlyArray<A>, refinement: (a: A, i: number) => a is B): self is ReadonlyArray<B>; <A>(self: ReadonlyArray<A>, predicate: (a: A, i: number) => boolean): boolean; }
