Facebooks React 17 JavaScript library: Heres why its top feature is no new features
Summary
However, the project describes the latest release of Facebooks popular framework for building user interfaces for web apps as "unusual", because its a major release with no new features for developers. Additionally, it meant supporting deprecated application programming interfaces. This has worked out so far, but we are running into the limits of the all-or-nothing upgrade strategy," say Abramov and Nabors. This second approach could be ideal for larger apps that arent actively maintained and version 17 helps ensure these developers dont get stuck on an old version of React. While React 17 does have potentially breaking changes, the major release introduces changes to just 20 components out of 100,000, making it less risky for developers to upgrade to React 17.
