On React Native performance

On React Native performance

This is the post-mortem report about the performance problems found mostly in Android but also, in a lesser extend in iOS.

__DEV__ = false

This has a huge impact in the performance. By my measures, about 4x times faster. So be sure to that the app is

View index.js
class MyComp extends React.Component {
render() {
// copy props shallowly, you can use other technics such as lodash cloneDeep, et al
// Why do this? because props are inmutable
let props = Object.assign({}, this.props);
delete props.unwantedProp1
delete props.unwantedPropN
// You can also achieve all this with lodash.omit
View react-reusable-form.js
class Form extends React.Component {
constructor(props) {
this.state = {
name: '',
email: ''
handleNameChange(e) {
