  1. Server-sent events

    Method of continuously sending data from a server to the browser, rather than repeatedly requesting it (EventSource interface, used to fall under HTML5)

  2. IntersectionObserver

    API that can be used to understand the visibility and position of DOM elements relative to a containing element or to the top-level viewport. The position is delivered asynchronously and is useful for understanding the visibility of elements and implementing pre-loading and deferred loading of DOM content.

  3. IntersectionObserver V2

    Iteration on the original API that also reports if the element is covered by another element or has filters applied to it. Useful for blocking clickjacking attempts or tracking ad exposure.

  4. Mutation Observer

    Method for observing and reacting to changes to the DOM. Replaces MutationEvents, which is deprecated.

  5. Resize Observer

    Method for observing and reacting to changes to sizes of DOM elements.

  6. Server Timing

    Mechanism for web developers to annotate network requests with server timing information.

  7. Server Name Indication

    An extension to the TLS computer networking protocol by which a client indicates which hostname it is attempting to connect to at the start of the handshaking process.
