HTTP/2

HTTP/2 is a major revision of the HTTP network protocol used for communication on the web, designed to improve performance and efficiency over its predecessor HTTP/1.1. It introduces features like multiplexing, header compression, and server push to reduce latency and optimize data transfer between clients and servers.

Also known as: HTTP2, HTTP 2.0, h2, HTTPv2, Hypertext Transfer Protocol Version 2

Why learn HTTP/2?

Developers should learn and use HTTP/2 when building modern web applications to enhance speed and user experience, especially for sites with many resources or high traffic. It is essential for performance-critical use cases like e-commerce platforms, streaming services, and real-time applications where reduced latency and efficient resource loading are crucial.
