Answer 1

What version of React Native are you running? And what phone are you running it on?

If you run React Native on an Android Emulator, it'll be pretty slow. Also, if you have chrome debugging on, it slows the app down a LOT.

I'm running a fairly simple React Native app on my Samsung Galaxy s4 device, and it runs fairly quickly (animations run pretty smoothly too).

some example code that I run (a sidedrawer and main view with animation):

_renderCancel: function(){
  if (this.state.showView) {
    return (
      this.props.view
    );
  } else {
     return ;
   }
},

render: function() {

var menu = ;


return (
  
    
       
      {this._renderCancel()}   
    
  

);
},

this runs fairly quickly on my device.
