The Joy of Composition - Why stateless rendering is pure bliss

The Joy of Composition

Why stateless rendering is pure bliss

React just got stateless components, meaning that they are in essence pure functions for rendering. Pure functions make it dead simple - even fun - to refactor your views

Deprecating transferPropsTo

Deprecating transferPropsTo

It's a common pattern in React to wrap a component in an abstraction. The outer component exposes a simple property to do something that might have more complex implementation details.

We used to have a helper function called transferPropsTo. We no longer support this method. Instead you're expected to use a generic object helper to merge props.

render() {
 return Component(Object.assign({}, this.props, { more: 'values' }));
