HTML5 + JavaScript

HTML is the markup used to render Web pages.

HTML5 app development can be preferable to building native apps because you usually only have to code the app once, then you can bundle the code in different ways: whether for iOS devices, Android devices, desktop computers, etc. This is pretty neat as it means a reduction in development time and maintenance costs.

Key Features

  • Device agnostic.
  • Can be used for apps and Web pages.
  • Responsive design to fit any device or screen size.
  • Built-in media playback that requires no third-party tools.
  • Offline caching, which allows certain elements to be accessed offline.

However, even with these benefits, there is a trade-off in performance. Native applications have access to the entire operating system’s development framework, which is optimized to give the best performance. HTML5 apps might be great for flexibility and cross-platform feasibility, it can result in below-average app performance.

If your app needs access to hardware on the device, like the camera, this can also be difficult using HTML5.

There is a way around this, which is to use the best-of-both-worlds approach of creating a “hybrid app”, which is an HTML5 app inside a native app wrapper. This allows for the flexibility and lower maintenance requirements of HTML5, while wrapping the app to provide operating system functionality and interface elements to make the experience more native and intuitive to the user.
