WebSocket是客戶端和伺服器之間的持久連接。 WebSocket提供了雙向，全雙工通信通道，該通道通過單個TCP / IP套接字連接在HTTP上進行操作。 WebSocket協議的核心是促進客戶端和伺服器之間的消息傳遞。
伺服器發送事件（SSE）：這是一種伺服器推送技術，使客戶端能夠從伺服器接收自動更新。

  3. For Slow internet/ Bad connection what should be used?
    http long Polling or WebSockets?
    For Platforms like live Chess games, where every second matters!!!

  4. Awesome! Thank for this video first of all 🙂
    Please help me with the following questions.
    Http Long polling :
    1. should the edge case of a change in Internet connection(on and off), be handled by the developer
    2. Is there any limit to the number of handshakes per day, if there is no response from the server in 24 hrs

    WebSocket:
    1. Since this is the best solution, the connection has to be established every time where there is connection change? (edge case to be handled?)

    Server-Sent Events:
    Can this solution be applied to cab applications and food delivery applications as well in addition the stock market example discussed?
