/**
* Creates a duplicate-free version of an array.
*
* This function takes an array and returns a new array containing only the unique values
* from the original array, preserving the order of first occurrence.
*
* @template T - The type of elements in the array.
* @param {ArrayLike<T> | null | undefined} arr - The array to process.
* @returns {T[]} A new array with only unique values from the original array.
*
* @example
* const array = [1, 2, 2, 3, 4, 4, 5];
* const result = uniq(array);
* // result will be [1, 2, 3, 4, 5]
