Module 1: Quick Review of TypeScript
  • Why Typescript is such a stonkingly good idea
  • Remember – Typescript is (currently) design-time only
  • Adding TypeScript to existing JS files
  • Use as little or as much TypeScript as you like
  • Towards an agreed code style: using TypeScript consistently
  • Get out of jail free with type and its relatives (and when not to use them)
  • Checking against permitted members with Type Guards
  • Partial, ReturnType, Required and other Utility types
  • Assigning Type based on conditions
  • Deriving Types from collection index members
  • New types for old with maps types
  • Keeping up with the code-ashians: ECMAScript just keeps getting better every year
  • What’s new since ES6:
  • …and you are making use of back ticks and interpolation, aren’t you?
  • So how do we do it this week?
  • Who’s driving the ECMAScript agenda (and how you can have your say)
  • What’s coming
  • Why pure functions turn out to be a good idea
  • Scalable encapsulation, testability and stateful apps
  • What that means for coding style
  • Are we there yet? What the RxJS library is teaching ECMAScript
  • Exploring functional helpers and the underlying thinking
  • Popular helpers from lodash
  • Benefits when it comes time to test
  • Close of Day Discussion and Q&A
  • Can we fix it? Yes we can
  • Can we fix it? Yes we can and so can my wife
  • These types are really cool … and flexible!
  • Modules and Namespaces
  • Import, Export (and not a trade deal in sight)
  • Dependency injection, inversion of dependency and all that jazz
  • These aren’t just and old components, they’re namespaced components
  • Towards architectural conventions
  • Automated tree-shaking, dehydration and module refactoring (oh my!)
  • When you say compile, you really mean…
  • The wonderful world of automated testing
  • So how do we do it this week?
  • Who’s driving the ECMAScript agenda (and how you can have your say)
  • What’s coming next
