Package: effect
Module: Array

Array.splitWhere

Splits an iterable at the first element matching the predicate. The matching element is included in the second array.

When to use

Use when you need to split an array at the first element that marks a condition boundary.

Example (Splitting at a condition)

import { Array } from "effect"

console.log(Array.splitWhere([1, 2, 3, 4, 5], (n) => n > 3)) // [[1, 2, 3], [4, 5]]

See

• span — splits at the first element that fails the predicate
• splitAt — split at a fixed index

Signature

declare const splitWhere: { <A>(predicate: (a: NoInfer<A>, i: number) => boolean): (self: Iterable<A>) => [beforeMatch: Array<A>, fromMatch: Array<A>]; <A>(self: Iterable<A>, predicate: (a: A, i: number) => boolean): [beforeMatch: Array<A>, fromMatch: Array<A>]; }
