Package: effect
Module: Tuple

Tuple.appendElements

Concatenates two tuples into a single tuple.

When to use

Use to append all elements from one tuple to another tuple.

Details

The result type is [...T1, ...T2], preserving all element types from both tuples. Neither input tuple is mutated; a fresh tuple is returned.

Example (Concatenating tuples)

import { pipe, Tuple } from "effect"

const result = pipe(Tuple.make(1, 2), Tuple.appendElements(["a", "b"] as const))
console.log(result) // [1, 2, "a", "b"]

Signature

declare const appendElements: { <const T2 extends ReadonlyArray<unknown>>(that: T2): <const T1 extends ReadonlyArray<unknown>>(self: T1) => [...T1, ...T2]; <const T1 extends ReadonlyArray<unknown>, const T2 extends ReadonlyArray<unknown>>(self: T1, that: T2): [...T1, ...T2]; }
