PhoneGap&#x2F;Cordova apps are slow. Very slow. And even a hello world app can weigh tens of MB. Debugging is painful compared to a native app.<p>The thing is, you won&#x27;t notice how bad the situation actually is until your code base has grown. Performance can seem acceptable at first, when there&#x27;s very little code to load and run. When your codebase inevitably grows, you&#x27;ll start noticing slow start up times (&gt; 10 seconds) and a laggy UI.<p>If you have to do any computationally intensive operation, you&#x27;ll have to resort to cordova plugins because JS running in the UI thread is a non-starter.
