React Notes

• A React component can only return one parent element.

return <h1>Hello</h1><p>World</p>            // error
return <div><h1>Hello</h1><p>World</p></div> // okay 

• JavaScript expressions can be interpolated in JSX with {}

The gist: by having a Promise adopt the state of a forever pending one, you can suspend its then handlers chain.

Promise.pending = Promise.race.bind(Promise, [])

let cancel

new Promise(function(fulfill, reject) {
  cancel = function() {fulfill(Promise.pending())}
  setTimeout(fulfill, 1000, 5)
