3### Introduction
4
5This sample implements a simple calculator app using JS distributed features. The calculator can perform simple numerical calculations and start a remote calculator Feature Ability \(FA\) to perform collaborative calculation.
6
7- Remote startup: **StartAbility** is used to start a remote app.
8- Collaborative calculation: The **DistributedDataKit** distributed data framework is used to implement data synchronization between remote applications.
