Deep sleep not working in ESP32

hi ,

I am using esp32 huzza32 board . i want to deepsleep my device for several time . but i am unable to sleep my device it restart but never sleep.

My code:

E.on('init',function() {

digitalWrite(new Pin(13), 0); 
var count = 0 ;  
setInterval(function() {   
  count++;     
    console.log(count);
    if(count >= 10 ){
       ESP32.deepSleep(100000);
    }
}, 100);

});

Output :
