/**
 * @description
 * Creates a duplicate-free version of an array. Uniqueness of elements is determined by
 * the result of passing each element to the `iteratee` function.
 * The order of result values is determined by the order they occur in the original array.
 * This function is similar to lodash's `uniqBy`.
 *
 * @param {List<T> | null | undefined} array - The array to inspect. If null, undefined, or not an array-like object, an empty array is returned.
 * @param {ValueIteratee<T>} iteratee - The function invoked per element to generate the criterion for uniqueness.
 * It receives three arguments: (value: T, index: number, collection: List<T>).
 * @returns {T[]} Returns the new array of unique elements.
