today when i want to write a demo to practice React,I met a problem about getInitialState and constructor,now I understand the difference lie in we use ES6 or ES5 grammer,the following example explain it,so we should notice about ES6 grammer in React, it very easy made me make a mistake
- ES5
var TodoApp = React.createClass({
getInitialState () {
return {
items: []
};
}
});
- ES6
class TodoApp extends React.Component {
constructor () {
super()
this.state = {
items: []
}
}
});
