JSX Spread Attributes

If you know all the properties that you want to place on a component a head of time, it is easy to use JSX:

  var component = <Component foo={x} bar={y} />;

Mutating Props is Bad, mkay

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' }));

React-Core Meeting Notes 2015-03-20

Note: This is the first time we're sharing meeting notes publicly. The primary reason we haven't shared these is because we often mix public discussions with matters that are Facebook specific and should not be public. We're really trying to be more open about our development process and what's happening inside the project so moving forward, we'll be sharing meeting notes. While most of us do work at Facebook, we're committed to this being an open project - for now we'll filter out the private notes from the public notes. Hopefully we can make it possible for these meetings to be open to any who wish to attend.

<Comp key={1} /><Comp key={1} />

• Preserve component state across different parents:
