Handling GET and POST Parameters

In web development, servers often need more information from clients to provide meaningful responses. Parameters are the pieces of data that clients send to servers to specify exactly what they need. By handling parameters effectively in our Node.js server, we can create dynamic applications that respond intelligently to user input.

Think about when we search for a product online or view a specific user's profile:

• When we search, our query (e.g., "node.js books") is sent to the server as a parameter, so it knows what results to return.

• When we view a profile, the user ID in the URL tells the server which user's information to display.

• When we submit a form, the data we enter is sent as parameters for the server to process.
