The answer is no. The goal between the two are very different. There is even an RFC for WebSocket over HTTP/2 which allows you to make multiple WebSocket connections over a single HTTP/2 TCP pipe..
Then, can WebSocket replace HTTP?
HTTP/2 is not a replacement for push technologies such as WebSocket or SSE. HTTP/2 Push server can only be processed by browsers, not by applications.
Similarly, does pusher use WebSockets? Pusher is a proxy service that sits between your clients and server. On the client, Pusher provides a range of WebSocket libraries for JavaScript, iOS, Android, Flash, . On the server, Pusher provides a range of WebSocket libraries for PHP (generic and framework options), Ruby, ASP.NET (C# and VB.NET), Python, Node.
Also to know, what is the difference between socket and WebSocket?
WebSockets typically run from browsers connecting to Application Server over a protocol similar to HTTP that runs over TCP/IP. So they are primarily for Web Applications that require a permanent connection to its server. On the other hand, plain sockets are more powerful and generic.
Is WebSocket asynchronous?
Websocket connections are fully asynchronous, unlike HTTP/1.1 (synchronous) and HTTP/2 (asynchronous, but the server can only initiate streams in response to requests). With Websocket, the client and the server can both send frames at any time without any restriction. Websocket is an IETF standard.

Are WebSockets restful?
WebSocket is a stateful protocol whereas REST is based on stateless protocol i.e. client does not need to know about the server and same hold true for the server. WebSocket connection can scale vertically on a single server whereas REST, which is HTTP based can scale horizontally.Does Facebook use WebSockets?

What technology does Google Drive use to do real-time? When I type in a Google Drive document that is being accessed by multiple users, the Chrome Developer Tools Network tab shows that there are no WebSockets.Do you really need WebSockets?
WebSockets provide us communication in full-duplex mode, that means the client can send and receive messages on the same channel. This is an advantage of course, and it improves performance and user experience a lot, but in case of standard real-time applications, we do not need full-duplex communication.How many WebSockets can a server handle?
65,536 sockets
When should I use WebSockets?
When a client needs to react quickly to a change (especially one it cannot predict), a WebSocket may be best. Consider a chat application that allows multiple users to chat in real-time. If WebSockets are used, each user can both send and receive messages in real-time.Is WebSocket faster than HTTP?
In many web applications, websockets are used to push messages to a client for real-time updates. Usually we recommend using a websocket connection when getting started with Feathers because you get real-time updates for free and it is faster than a traditional HTTP connection.Are WebSockets still used?
WebSockets are a part of the HTML5 spec and they are supported by all modern browsers (meaning, there is a JS API to use them natively in the browser).What are WebSockets good for?
WebSockets enables instant data exchange and is supported by all modern browsers. Put it to use immediately in your Web apps. Users now demand information as soon as it's available. Luckily, a protocol supported by all modern browsers allows for direct data exchange: WebSockets.Why do we need WebSockets?
With WebSocket, your HTTP request becomes a single request to open a WebSocket connection and reuses the same connection from the client to the server, and the server to the client. 2-WebSocket reduces latency. For example, unlike polling, WebSocket makes a single request. WebSocket is an innovation in performance.Does WhatsApp use WebSockets?
Protocol used by WhatsApp The primary protocol in use is XMPP (Extensible Messaging and Presence Protocol). Additionally, Whatsapp uses HTML5 WebSockets which communication technology which facilitates two-way communication.What are WebSockets how is it different from HTTP?
HTTP and WebSocket are protocol, which is used for transferring/rendering of data. HTTP is a uni-directional communicational protocol, whereas WebSocket is bi-directional. Whenever a request is made through HTTP, it creates a connection at the client(browser) and closes it once the response from the server is received.What is Web socket in Java?
18 Java API for WebSocket. WebSocket is an application protocol that provides full-duplex communications between two peers over the TCP protocol. In the traditional request-response model used in HTTP, the client requests resources, and the server provides responses.What is WebSocket communication?
WebSocket is a communications protocol for a persistent, bi-directional, full duplex TCP connection from a user's web browser to a server. A WebSocket connection is initiated by sending a WebSocket handshake request from a browser's HTTP connection to a server to upgrade the connection.What is Ajax used for?
AJAX = Asynchronous JavaScript and XML. AJAX is a technique for creating fast and dynamic web pages. AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page.What is TCP client?
TCP Client/Server Communication. Establishes a two-way connection between a server and a single client. Provides reliable byte stream transmission of data with error checking and correction, and message acknowledgement.What is socket connection?
A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.
