What's Expected from React, Angular, and Vue in 2017
Browser-based React was relatively quiet in 2016. Version 15.0 was released in April, the only such major upgrade, though there were consistent minor updates throughout the year. In 2017, we'll start to hear more about React Fiber, which is described as an "ongoing reimplementation of React's core algorithm". Dan Abramov says that "there is still quite a bit of work to do", but that it should land in version 16.0 or 17.0 of React.
Much of the React team's work is on getting Fiber out the door in 2017, but it's a significant change. Fiber is a "complete rewrite of React", although the goal is to "maintain backwards compatibility wherever possible". Once Fiber is in place, Facebook hopes to enable "web apps with 60 fps and animations".
For Angular, 2016 was filled with uncertainty. As the weeks ticked off, Angular 2 seemed to grow, encompassing more use cases and always just out of reach. Finally released in September, it landed as one of the most complete platforms developers could choose.
On the roadmap for 2017 is the release of Angular 4. Technically it will include breaking changes, but it will not be the same sort of drastic change as 1 to 2. As developers become more familiar and comfortable with the Angular 2 platform and TypeScript, 2017 should see maturation and growth of Angular 2 and its ecosystem.
To be fair
