What is your display brand/model number? Some of those SSD1306 displays have different connections internally and need different initialisation codes :(

You can't flash the nRF52DK using the Web IDE. However if what you're asking is how to write your JS code in to flash, you type save() on the left-hand side.

It's worth going through the getting started tutorial as it'll explain it: http://www.espruino.com/Quick+Start

yes. Understood)
Now i defined ble service:

//Start BLE service
NRF.setServices({
  0xABCD : {
    0xDCBA : {
      value    : 0x01,
      //maxLen   : 1,
      writable : true,
      readable : true,
      onWrite  : function(evt) {
        digitalWrite([LED3,LED2,LED1], evt.data[0]);
      }
    }
  }
});

it works while i am not saving program in flash. After saving my service disappears
