Express middleware acts like a toolbox for your web server, enabling you to customize how it manages requests and responses. It’s a handy set of tools, that enhances Express’s flexibility for specific tasks and gives you control over your server’s capabilities

Purpose of the body-parser Middleware in Express:

• Data Handling: body-parser is a middleware in Express designed to handle and parse data sent in the body of HTTP requests.
• Request Body: It specifically focuses on extracting data from the request body, which is commonly used for submitting information through forms or API requests.
• Data Format: The middleware formats the data into a usable structure, often a JavaScript object, making it easier for the server to work with the information.
• JSON and URL-encoded Data: body-parser supports parsing data in various formats, including JSON and URL-encoded data, providing flexibility for different types of requests.
• Simplifying Processing: It simplifies the process of handling incoming data, allowing developers to seamlessly integrate and use user-submitted information in their Express applications.

So, body-parser is like a helper that takes the data sent by users, organizes it, and makes it ready for your Express\ server to use.
