Create React App 2.0 has been released today, and it brings a year’s worth of improvements in a single dependency update. While React itself doesn’t require any build dependencies , it can be challenging to write a complex app without a fast test runner, a production minifier, and a modular codebase. Since the very first release, the goal of Create React App has been to help you focus on what matters the most — your application code — and to handle build and testing setup for you. Many of the…![]()

This is why we called it React.memo rather than React.pure. (No, function components aren’t memoized by default.) It’s confusing naming in retrospect and we need to break the cycle. Memoization is the right concept but it’s too hard to spell so we went with “memo”.

Looks like React-Redux v5 may not work okay with React 16.6's new `React.memo()` API . `connect` doesn't accept the new built-in component types.
This will be fixed in React-Redux v6. Please try our `next-995` and `next-1000` tags and let us know if they work better!

If I had to condense my talk into a single frame, it would be this one. Hooks let you define your own abstractions (like useWindowWidth in this example) that “feel” as natural to use as React’s built-in features.
