There is a discussion in progress about a JavaScript framework for WordPress. The discussions are primarily focused on React or Vue.js. While the general consensus seems to be that Vue.js is “approachable and highly extensible,” React might be the winner if only to follow in the footsteps of projects like Calypso. Matt even mentioned that React was a “long term bet” back in December.
Developers should voice their opinions and monitor this conversation as it progresses. Any decisions that are made will have a long term impact on WordPress core.
