Wat is Cordova?
Apache Cordova is an open-source framework that allows web developers to use their HTML, CSS and JavaScript content to make a native application for different mobile platforms. Cordova takes a web application and renders it in a native WebView. A WebView is a type of screen that is used to show web content within a native app. It is a sort of web browser without the standard UI elements, like an address entry or status bar.
What does a Cordova developer do?
A Cordova developer has experience with creating hybrid applications. In fact, you should see a Cordova programmer as a hybrid developer. They are knowledgeable about app development: how Android and iOS are wired, but also web development: how to make quick, functional web apps using HTML/CSS/JavaScript. Cordova developers are able to combine two components into a consistent and modern final product.
Cordova developers are seen as web app developers with affinity for mobile platforms. Cordova programmers are often faster at creating apps, since developing hybrid apps costs less time than creating an app for each individual native platform.
