• Practical Performance Tips to Make Your Cross Platform Mobile Apps Faster

  5:00 PM Saturday   Room: R2-222

  Apache Cordova is one of the most popular frameworks for cross-platform mobile development. Web developers can build apps for iOS, Android, and Windows based on the same frameworks they use for the Web by using a shared codebase. However, the methods for improving mobile app performance can be different from those web developers use for web apps. Doris Chen outlines what impacts “native performance” and explains how the startup time, as well as the overhead of resume, memory, communication, and the Web, can all contribute to the performance of Cordova apps. To build Cordova apps that perform well, it’s important to understand how to avoid common pitfalls and how to use the technologies in the most efficient ways. Doris introduces tools for performance tests and demonstrates how to measure mobile app performance by using diagnostic tools for different platforms. Doris also shares practical tips for building faster Cordova apps by exploring Document Object Model (DOM) complexity, animation techniques, and memory management.

• What's New in TypeScript?

  1:45 PM Saturday   Room: RG-248

  TypeScript has seen enormous growth over the past year. Today, it is used to build several key frameworks like AngularJS, Ionic etc. In this talk, Doris will go through how TypeScript enables you to leverage features from the current and future of JavaScript while increasing the productivity of JavaScript development across the board. As ECMAScript 6 gains popularity and more browsers are implementing the standard, JavaScript developers are beginning to wonder, 'what's next?' This session will cover some of the latest features of TypeScript, including future ECMAScript proposals, support for Angular and React/JSX, the state of the art type system capabilities, and how it all comes together to make working and creating things in JavaScript more productive and fun with TypeScript.

• Practical Performance Tips and Tricks to Make Your HTML/JavaScript Faster

  9:45 AM Saturday   Room: S-140

  How to tackle real-world web platform performance problems in modern websites and apps? This session starts with a basic understanding of the web platform and then explores to a set of problem/solution pairs built from industry-standard performance guidance. In the talk, Doris will demonstrate performance tips and tricks that will help you to improve the performance of your apps and sites today. She will discuss the following respond to network requests, speed and responsiveness, optimizing media usage, and writing fast JavaScript. These performance tips and tricks apply equally to web sites that run on standards based web browsers, as well as to modern apps.
