My answer explained that Express is generally used to create a server. I proceeded to write the code to import the Express package and demonstrated how we use an Express object to define endpoints. Additionally, I outlined the steps to set a port number for the server to listen to incoming client requests, and I mentioned that we use the listen method on the Express object to open the port and enable it to receive requests. I also highlighted that, when defining endpoints, we can include functions to validate request parameters, along with middleware to log API requests and responses.
