server.on("/"): This line sets up a handler for a specific route on the server. In this case, it's the root URL ("/"), which is the default entry point when someone accesses your server.
HTTP_GET: This specifies the type of HTTP request that this handler will respond to. In this case, it's an HTTP GET request. GET requests are commonly used when a client wants to retrieve data from the server.
[](AsyncWebServerRequest *request) {...}: This is a C++ lambda function. It's an anonymous function defined inline. The function takes one parameter, which is a pointer to an AsyncWebServerRequest object. This object represents the incoming HTTP request. - วิทยาศาสตร์และเทคโนโลยี
