Module: Chunk

Chunk.difference

Creates a Chunk of values not included in the other given Chunk. The order and references of result values are determined by the first Chunk.

Example (Computing chunk difference)

import { Chunk } from "effect"

const chunk1 = Chunk.make(1, 2, 3, 4, 5)
const chunk2 = Chunk.make(3, 4, 6, 7)
const result = Chunk.difference(chunk1, chunk2)
console.log(Chunk.toArray(result)) // [1, 2, 5]

// String difference
const words1 = Chunk.make("apple", "banana", "cherry")
const words2 = Chunk.make("banana", "grape")
const wordDiff = Chunk.difference(words1, words2)
console.log(Chunk.toArray(wordDiff)) // ["apple", "cherry"]

// Empty second chunk returns original
const empty = Chunk.empty<number>()
const unchanged = Chunk.difference(chunk1, empty)
console.log(Chunk.toArray(unchanged)) // [1, 2, 3, 4, 5]

Signature

declare const difference: { <A>(that: Chunk<A>): (self: Chunk<A>) => Chunk<A>; <A>(self: Chunk<A>, that: Chunk<A>): Chunk<A>; }
