/**
|
|
* Creates a function that removes a number of values from the start of an array.
|
|
*
|
|
* Negative counts are treated as 0, matching the main {@link drop}
|
|
* implementation. The returned function is lazy-capable inside {@link pipe}.
|
|
*
|
|
* @template T - The type of elements in the array.
|
|
* @param count - The number of values to skip from the start.
|
|
* @returns A function that maps the piped array to the remaining suffix.
|
|
*
|
|
* @example
|
|
* import { drop, pipe } from 'es-toolkit/fp';
|
|
*
|
|
* pipe([1, 2, 3, 4], drop(2));
|
|
* // => [3, 4]
