/**
 * Finds the minimum value in an array.

 * @template T - The type of elements in the array
 * @param array - The array to search
 * @param key - Optional key to find minimum value from objects
 * @returns The minimum value, or 0 if array is empty

 * @example
 * ```ts
 * min([3, 1, 4, 1, 5]); // 1
 * min([{ value: 5 }, { value: 2 }, { value: 8 }], 'value'); // 2
 * min([]); // 0
