- 3. Consulting/Training Long, long ago Seriously, we’re talking decades In a galaxy far, far away … OK, so not that far away … Someone got the bright idea that they would write a new language in just 10 days “I shall call it … Mocha! No, wait … LiveScript … or, let’s make it even more confusing … JAVASCRIPT! Muwahahahahahahahah” Once Upon a Time …

- 5. Consulting/Training Lightweight Scripting Language Easy to Learn Runs in Every Browser Dynamic by Nature Object-based Built from day one to understand JSON Just making sure you were awake The Pros of JavaScript
- 6. Consulting/Training Lightweight Scripting Language … asked to do heavyweight work on the client Easy to Learn think you’ve learned it Runs differently in Every Browser Dynamic by Nature Object-based … prototypical, which is a con when you are expecting object-oriented Let’s go back to pros … it thankfully doesn’t do well with SOAP The Cons of JavaScript
- 7. Consulting/Training Now we have to learn another language that behaves completely differently. Hoisting just doesn’t make sense and is only useful for JavaScript show-offs to stump their C#-loving enemies. Once you finally learn to use === instead of == some API returns “2” instead of 2 and everything breaks It’s tough to trust an API that takes any number of parameters without complaining It insists on a camel-case convention and then doesn’t complain when you accidently use Pascal case Function scope. Really? If I have to write another self-invoking function … What is this? I now need a Mac and Windows with 12 Virtual Machines just to test every combination of platform and browser we’re going to support The Enterprise at War
- 8. Consulting/Training JavaScript is here to stay You can probably thank smart phones HTML5 isn’t helping things either Not even the servers are safe with Node.js It’s OK, things are better … It’s Time to Bury the Hatchet
- 9. Consulting/Training 1995 – JavaScript ships 1995 – 2005 – Weeping and Gnashing of Teeth (although AJAX was available in 1999, it wasn’t even called that until 2005) 2006 – John releases jQuery and $ will never be the same 2008 – Engine gets a V8 (Google) 2009 – Jeremy releases CoffeeScript 2009 – Ryan releases Node.js 2010 – v1 of Knockout.js released 2011 – ECMAScript 5.1 provides hope for standards 2012 – TypeScript released (Microsoft) 2012 – v1 of Angular.js is released (after 3 years of development) 2013ish – asm.js (Mozilla) Important Milestones
- 10. Consulting/Training function (e) { return e.idx; } e => e.idx; for (var x = 0; x < 5; x++) { var y = x*2; } for (var x = 0; x < 5; x++) { let y = x*2; } const pi = "delicious."; class MyClass { constructor(a,b) { public a = a; private b = b; } get factor () { return private(this).b * a; } } // generators // modules // … and much, much more … ES6 – Living in Harmony
- 11. Consulting/Training Types Enumerations Generics Interfaces and Interface Extension, Implementation Optional Properties Classes with Inheritance Static and instance types Private and Public Modifiers Accessors Modules External Modules (node.js, require.js) Ambient Declarations Introducing TypeScript “Say hello to my little friend.”
- 12. Consulting/Training Immediate reduction in defect rates Faster ramp-up for new developers Shorter time to learn new APIs Accelerated rate to get from “file -> new” to “story done” C# developers spend less time asking themselves, “What is this?” Code is easier to understand and maintain Saying “refactor” no longer results in weird stares and people trying to usher you into a back room Bottom line: Estimated 2 – 4x improved productivity. Before: Eight 2-Week Sprints. After: Four 2-Week Sprints. Before: 100 points / sprint. After: 250 points / sprint. Case Study
