es-toolkit/dist/fp/array/compact.js

A state-of-the-art, high-performance JavaScript utility library with a small bundle size and strong type annotations.

const require_compact = require("../../array/compact.js");
const require_lazy = require("../_internal/lazy.js");
//#region src/fp/array/compact.ts
/**
* Creates a function that removes falsey values from an array. Use it with {@link pipe}.
*
* Falsey values include false, null, 0, -0, 0n, an empty string, undefined,
* and NaN. The returned function is lazy-capable inside {@link pipe}, so a
* trailing short-circuiting operator such as {@link take} can stop once enough
* truthy values have been emitted.
*
* @template T - The type of elements in the array.
* @returns A function that maps a readonly array to a new array with falsey values removed.
*
* @example
* import { compact, pipe } from 'es-toolkit/fp';
*
* pipe([0, 1, false, 2, '', 3], compact());
* // => [1, 2, 3]
