ReactJS: setTimeout() not working?

Question

Having this code in mind:

var Component = React.createClass({

    getInitialState: function () {
        return {position: 0};    
    },

    componentDid         


        

Answer 1

setState is being invoked immediately due to the parenthesis! Wrap it in an anonymous function, then call it:

setTimeout(function() {
    this.setState({position: 1})
}.bind(this), 3000);
