From this episode:

“One thing that’s really cool about the direction that typed JavaScript is going, with both Flow and TypeScript is that you have the ability to go in and you have this type checker that can inform you when you’ve made these breaking changes. You can also still make those breaking changes and expect the code to run; compiling isn’t a precursor to running.”

Picks, Links and Tips from this episode


Anders Heljsberg, @aheljsberg

  • Follow your passion. Go Play. Write some new code. That’s how you do your best work. Try to enjoy what you’re doing.
  • There are lots of people coming to JS now. Lots of OOP programmings flowing into the ecosystem. JS can be a great FP language though. There’s a lot you can learn from studying FP in JS.

Jeff Morrison, @lbljeffmo

Links Tips
  • Have a “just get it working” mentality. Then clean it up after

Brian Lonsdorf, @drboolean

  • Functions should be input to output. Type systems help a lot more when you compose this way.
  • Stay away from Object|Any :)

  • No matter how well you know something, keep your mind open to learn even more about it.
