union

function Array.union<T>(
    target: readonly T[],
    source: Iterable<NoInfer<T>>,
): readonly T[]

Returns a new array containing all unique elements from both target and source. Elements from source that are not already in target are added to the result.

Example

data-first

import { Array } from "@monstermann/array";

Array.union([1, 2, 3], [3, 4, 5]); // [1, 2, 3, 4, 5]

data-last

import { Array } from "@monstermann/array";

pipe([1, 2, 3], Array.union([3, 4, 5])); // [1, 2, 3, 4, 5]
