Package: effect
Module: Chunk
Takes all elements so long as the predicate returns true.
Example (Taking elements while a predicate matches)
import { Chunk } from "effect"
const chunk = Chunk.make(1, 2, 3, 4, 3, 2, 1)
const result = Chunk.takeWhile(chunk, (n) => n < 4)
console.log(Chunk.toArray(result)) // [1, 2, 3]
// Empty if first element doesn't match
const none = Chunk.takeWhile(chunk, (n) => n > 5)
console.log(Chunk.toArray(none)) // []
// Takes all if all match
const small = Chunk.make(1, 2, 3)
const all = Chunk.takeWhile(small, (n) => n < 10)
console.log(Chunk.toArray(all)) // [1, 2, 3]
