/**
 * Creates a predicate function that determines if a value exists in a given array.
 *
 * @template T - The type of the array elements and value
 * @param array - The array to search within
 * @param value - The value to check for
 *
 * @remarks
 * - Pure function with no side effects
 * - Uses Array.prototype.includes() for membership testing
 * - Uses strict equality (===) for element comparison
 * - Works with any type that can be compared with strict equality
 * - Useful for array filtering and validation predicates
 *
 * @example
 * ```typescript
 * const isValidStatus = isIn(['pending', 'approved', 'rejected']);
 * isValidStatus('pending');  // true
 * isValidStatus('unknown');  // false
 *
 * const isPrime = isIn([2, 3, 5, 7, 11, 13]);
 * isPrime(7);  // true
 * isPrime(10); // false
 *
 * // Useful with arrays
 * const userIds = [101, 102, 103, 104];
 * const activeUsers = [101, 103, 105, 106];
 * const validActiveUsers = activeUsers.filter(isIn(userIds)); // [101, 103]
 * ```
