PhoneGap, also called Apache Cordova, is an open source hybrid mobile application development framework. It uses standard and well-known web technologies such as HTML, Cascading Style Sheets (CSS), and JavaScript to create cross-platform mobile applications without using native development languages.

If you want to develop a native Android application, you should know APIs related to Java and Android SDK. For an iPhone app, you need to know Objective-C or Apple's new Swift language. Similarly, for all other mobile platforms, you need to know their respective programming languages. The code you write for one platform does not work for another platform. To overcome these difficulties, we now have a hybrid mobile development framework called PhoneGap. The applications that you develop using PhoneGap can be deployed on several other platforms. It's a write-once-deploy-everywhere kind of framework.

The following is the list of mobile platforms currently supported by PhoneGap:

The framework enables developers to access all the hardware-dependent features using simple JavaScript. Developers will be able to access device contacts, location, files, device information, and much more, with simple functions. Note that a new platform called "browser" is now supported. Sound interesting? It is left up to you to increase your curiosity.
