HTTP/3
HTTP/3 is the third major version of the Hypertext Transfer Protocol (HTTP), designed to improve web performance and security by using QUIC as its underlying transport protocol instead of TCP. It reduces latency through features like multiplexing without head-of-line blocking and built-in encryption, making it particularly effective for modern web applications with high interactivity and real-time data needs.
Developers should learn and use HTTP/3 to enhance web application performance, especially for latency-sensitive use cases like video streaming, online gaming, and real-time communication. It is increasingly supported by major browsers, servers, and CDNs, making it essential for optimizing user experience in high-traffic environments and improving security with mandatory TLS encryption.
