Google Launches Drive Realtime API To Let Developers Build Apps With Real-Time Collaboration. Google just announced the launch of its Google Drive Realtime API, a new tool for developers that will allow them to bring the same real-time collaboration features that power Google Drive to their own apps.
The API, Google writes, “handles network communication, storage, presence, conflict resolution, and other collaborative details so you can focus on building great apps.” Google partnered with three-developer focused tools, the collaborative code editor Neutron Drive, the project scheduling tool Gantter and the diagraming tool draw.io to test and launch this API. To show off the power of the API, Google also developed a cube puzzle that uses the Realtime API, as well as a Drive Realtime API Playground for testing the API. Developers, of course, also need to sign up for the Drive API before they can use the Realtime API, too. Because the API tracks the collaborators’ presence, developers can alert users when others join, leave or make changes to a document. Understanding Design Patterns in JavaScript.

The inheritance examples we looked at last week used the form Rectangle.prototype = new Shape(). The reason I like this example is it shows how powerful prototypes are, despite their simplicity. The downside is the constructor for the parent object is executed, which isn’t always what’s desired. ECMAScript 5 introduced Object.create, which creates new objects based on a prototype object and an additional set of properties. The main differences between B.prototype = new A(); and B.prototype = Object.create(A.prototype) are as follows: Mozilla Popcorn. JavaScript HTML DOM Examples.
