[[React Native]], which enables native [[Android (operating system)|Android]], [[iOS]], and [[Universal Windows Platform|UWP]] development with React, was announced at Facebook's React Conf in February 2015 and open-sourced in March 2015.

===React Fiber===
'''React Fiber''' is a set of internal algorithms for rendering graphics used by the [[JavaScript]] library [[React (JavaScript library)|React]], as opposed to its old rendering algorithm, Stack. The actual syntax for programming with React does not change; only the way that the syntax is executed has changed.<ref name="techcrunch">{{cite web|url=https://techcrunch.com/2017/04/18/facebook-announces-react-fiber-a-rewrite-of-its-react-framework/|title=Facebook announces React Fiber, a rewrite of its React framework|website=TechCrunch|accessdate=2018-10-19}}</ref>
