/**
* Creates a function that takes leading values while a predicate returns true.
*
* The returned function is lazy-capable and short-circuiting inside
* {@link pipe}; once the predicate returns false, upstream lazy operators stop
* processing further input.
*
* @template T - The type of elements in the array.
* @param predicate - Called with each value and index until it returns false.
* @returns A function that maps the piped array to the matching prefix.
*
* @example
* import { pipe, takeWhile } from 'es-toolkit/fp';
*
* pipe([1, 2, 3, 1], takeWhile(value => value < 3));
* // => [1, 2]
