es-toolkit/dist/fp/array/chunkBy.mjs

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

import { chunkBy as chunkBy$1 } from "../../array/chunkBy.mjs";
//#region src/fp/array/chunkBy.ts
/**
* Creates a function that splits consecutive elements whenever the derived key changes.
*
* The iteratee is called from left to right. A new chunk starts when its key differs
* from the previous key by strict inequality. Use the returned function with {@link pipe}.
*
* @template T - The type of elements in the array.
* @param iteratee - Called for each value to produce the comparison key.
* @returns A function that maps a readonly array to consecutive same-key chunks.
*
* @example
* import { chunkBy, pipe } from 'es-toolkit/fp';
*
* pipe([1, 1, 2, 3, 3], chunkBy(value => value));
* // => [[1, 1], [2], [3, 3]]
