0 likes463 views
The document discusses the Dart programming language and its applications in various companies such as Google, Netflix, and Soundtrap. It highlights Dart's features, including strong typing, data types, and method parameters, and explains how to run Dart applications in the Chromium browser or compile them to JavaScript. Additionally, it touches on Dart VM modes and interfaces used in development.
![Methods - Positional Parameters
• optional parameters specified with [ ]
• defaults with =](https://image.slidesharecdn.com/dartpresentation-140805111049-phpapp02/85/Dart-Another-Tool-in-the-Toolbox-13-320.jpg)
Dart: Another Tool in the Toolbox
- 1. Dart Another tool in the toolbox
- 2. http://blog.sethladd.com/2013/09/forms-http-servers-and- polymer-with-dart.html Client and Server We got both kinds, Client and Server!!!
- 3. Who uses dart • Google - Fiber, Apps, Election • Netflix - Security Monkey, integration with AWS • Soundtrap - Music Recording with browser and WebRTC • Blossom - Lean project mgmt tool • SonarDesign - where Jesse works! :)
- 4. How do I use it? • Run in Chromium Browser with DartVM • Compile to javascript
- 6. Data types • Num (base abstract type): • int double (concrete types for num) • String • Bool • List - no arrays !! • Map
- 7. Bool • Unlike JavaScript, 1 is not true • True is true • Everything else is false
- 8. Strongly typed / Optionally typed
- 10. Classes
- 12. Constructor
- 13. Methods - Positional Parameters • optional parameters specified with [ ] • defaults with =
- 14. Methods - Named Parameters • named parameters specified with {} • defaults with :
- 15. name (x) => expression Shorthand function
- 16. Anonymous Function FYI: fold is like inject/reduce in ruby Use the shorthand syntax
- 17. Generics
- 18. Mixins
- 20. Interfaces • Not strict, only warnings if you don't implement all the methods
- 21. Dart VM Modes • Checked - annotations (int, string, etc) throw exceptions if given invalid data • Production - type annotations are ignored
- 22. Console Apps • import "dart:io" • Can't use in web pages • File operations • synchronous • asynchronous
