In this repo, I have learned flashed message, performing authentication and authorization using MongoDB.
1.). Flash messages are short, temporary notifications that are used in web applications to give users feedback about their actions or status updates.
2.). Flash messages are designed to inform users about a specific event or action. They are often used to let users know if an action was successful or if there was an error.
3.). Flash messages appear on the screen briefly and then disappear. This temporary nature helps keep the user interface clean and uncluttered.
4.). Flash messages are commonly used in web development to communicate with users without permanently changing the page's layout or content.
