    // Example of using a plugin to access the device's camera
navigator.camera.getPicture(onSuccess, onFail, {
  quality: 50,
  destinationType: Camera.DestinationType.DATA_URL
});

function onSuccess(imageData) {
  var image = document.getElementById('myImage');
  image.src = "data:image/jpeg;base64," + imageData;
}

function onFail(message) {
  alert('Failed because: ' + message);
}
  3. Wide Platform Support: PhoneGap allows developers to target multiple platforms, including iOS, Android, Windows, and more. This flexibility makes it easier to reach a broader audience. 
    <!-- Example of PhoneGap configuration for multiple platforms -->
<platform name="ios">
