Sending a message to esp32 access point with javascript

The thing that I am trying to do is this:

1. Set an esp32 board as an access point.

2. Create a website where we can enter the credentials of the access point (ssid, pass), connect to it and then start exchanging messages with the board.

Now, after having set the esp32 as an access point, how can we connect to it with javascript and start exchaning messages ?

I am guessing I will have to use sockets, but I dont really know how to use them with javascript, and the information from the web for this topic is not really helpful for me.

Any guidance on how to achieve this or what to read would be appreciated. Thanks.

Edit: The website is running on an orange pi board.
