/**
* Invokes the getValue function n times, returning an array of the results.

* @param getValue - The function to invoke for each index.
* @returns An array containing the results of invoking getValue n times.
* @example
* times(3, (i) => i * 2); // => [0, 2, 4]
* times(2, () => 'es-toolkit'); // => ['es-toolkit', 'es-toolkit']
