Why Not Mix It Up? Link
Rather than build an app entirely with native or HTML5 technology, why not mix and match the technologies? With a hybrid application, building a mobile experience that leverages both native and HTML5 code for the user interface is quite possible. This enables the developer to use the most appropriate tool for the job when developing the user interface.
Clearly, developing portions of the user experience in two or more different technologies has some downsides. Chiefly, you would need developers who can handle both native development and HTML5. The portion of the user interface in native code couldn’t be readily used on other platforms and would need to be redeveloped. Given the broader scope of knowledge required by this technique and the difficulties outlined above, why would anyone want to embark on an endeavor that mixes user-interface technologies?
