1. A computing device comprising an operating system and comprising: one or more memories comprising computer-readable code; and one or more processors, configured in response to executing the computer-readable code to cause the computing device to perform: causing elements to be recognized that correspond to one or more browser-supported programming languages in an application by traversing a model of at least a portion of the application, wherein the recognized elements are those elements in the model that can be converted to native user interface elements in the operating system and rendered on a display of the computing device; converting the elements in the one or more browser-supported programming languages to native user interface elements; and causing the native user interface elements to be rendered on the display of the computing device, wherein a native rendering process performs at least the converting the elements and causing the native user interface elements to be rendered and a web rendering process performs at least the causing the elements to be recognized, and wherein the computing device is further caused to perform: performing a web rendering of the application and a native rendering of the application in parallel, at least by: the web rendering process, in response to a change in the model, calling the native renderer process to cause the native rendering process to render native user interface elements corresponding to recognized elements in a changed portion of the model; and the native rendering process, in response to an event occurring in the native rendering, injecting code corresponding to the event into the web rendering process to cause the web rendering process to react to the event, wherein the web rendering of the application comprises elements rendered by the web rendering process that are not recognized by traversing the model; and causing the web rendering process to be hidden from the display.
