expressjsHow do I create a GET route using Express.js?

To create a GET route using Express.js, you need to use the .get() method. This method takes two arguments: the route path, and a callback function. The callback function takes two arguments, request and response. The request argument is an object that contains information about the request, such as the query parameters, headers, and other data. The response argument is an object that allows you to send a response to the client.

Below is an example of a GET route:

app.get('/', (request, response) => {
  response.send('Hello, World!');
});

The code above will send the string Hello, World! to the client when the / route is requested.

The parts of the code above are:

• app: This is an instance of the Express application.
• .get(): This is the Express method for creating a GET route.
• /: This is the path of the route.
• (request, response): These are the arguments for the callback function.
• response.send(): This is a method for sending a response to the client.
