/**
|
|
* 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]
