Question

Messages from the server are received by ____

(a) onmessage

(b) send

(c) arrayBuffer

(d) blob

I had been asked this question in exam.

My doubt is from Web Socket Communications topic in section HTML Markup, Forms, Video, Audio & Other Multimedia of HTML

Answer 1

Correct answer is (a) onmessage

To explain I would say: onmessage function is used for receiving messages from the server. E.g. memeDocket.onmessage = function (eve) { console.log(eve.data); }. For sending data as a string we use ArrayaBuffer and Blob.
