TypeScript vs Elixir: An FP Showdown with Theo Browne | 021 

Cost per engineer is just one factor in a company and not the only one. In large companies efficient services can give a lot of leeway for other things . In our company we moved like 20 services from python to elixir and our cluster went from around 30 nodes minimum to 5. Its a huge savings and sets the precedent for efficient computing

Love it when a new episode drops as a drink my morning coffee!

okay this is definitely the best episode for me

4:45 - The reason Erlang works like it does is because it was designed by Ericsson to run big telecommunications networks - specifically telephony. It's one of the coolest languages and VMs ever. :)

This is fantastic! I don’t get to hear this side of Theo much. 👌🏽

Hey there, great show, great guests. Would you have more engineers from a FP background? I wonder if you tried weird stuff like Clojure and what you think how it compares to Golang …

Just randomly discovered your page and love it! The intro just dropping the nuke on Rust definitely got me interested in the rest of vid 👀

47:51 I’m doing the same thing right now at work. I’m rewriting a react app to typescript and I made a tool that makes an options call to a particular route in the api and converts it to a ts type/interface that I can then copy/paste. I thought I was being dumb but it brings me comfort to know Lane was doing the same thing lol

I think it's important to keep in mind that US engineers are significantly more expensive than anyone else

Let the banter begin 🏁🏁🏁

There was nothing oop about the old class based syntax that functional components changed in any way. The paradigm didnt change one bit. It was always a functional-ish framework and still is despite syntax changes.

Theo Browne!!!! WOOOOOWWW👌👌👌👌👌👌

I don't agree with the framing of strong statically typed vs dynamically/weakly typed systems, as FP vs OOP. Those are orthogonal concepts. You can have strongly statically typed OOP, and resolve dispatch at compile time (imagine C++ with a better type system), and just like match, it's has no run-rime cost. You can also have a dynamically typed FP language, and match will be evaluated at run time, just like virtual method dispatch.

Great episode 🎉🎉🎉

Why wasn’t ping made on Elixir?

Functional overloading is nice with curried functions. Read about data first vs operation first.

EffectTS Broskies - functional typescript.

This was great. Thanks

46:30 you might be interested in F# and its Type Providers. It can be used for similar kind of inference.

Honest question. Why do Go devs say that go is somewhat functional?

"I despise PHP and I still do, I get that it's productive but it's not a pleasant experience. It doesn't give me the joy of programming" This really hits home.

The jack of all trades like the legend plumber, doctor, astronaut,…

Awesome talk

39:10 "I'm gonna learn JavaScript" is not a goal. "You get good by getting your reps in" (in a specific thing).

55:00 Better off coming to the game late? I think it depends on what kind of engineer you are. If your goal is as weak as "to learn Rust", then yes, I'd agree. But if you've got the engineer mindset you build a lot of great stuff that gets lots of stars and such and gives you clout (and get that '5 years of experience' in the thing that hasn't even existed that long), and you know that lots of stuff sucks and needs change, but when it gets fixed you're excited to see it, right? I think the ambitious are better off getting in early, but the average are not. So... yes, the advice applies to most people.

47:50 htmx with Templ is interesting

'Backend as a service but your backend is the service' - did you just describe on-prem?

38:00 JSHint for the W. No config. Just JS.

i recommend looking up what happened to bob ross's business. it's a sad story there are some good articles on it

😮

Wow I can see where Theo is coming from...

Yeah but can he do a kick flip

Theo come back please

40:28 I would disagree and say you can learn a programming language if you’re only focused in syntax and semantics. However you’ll probably forget everything you’ve learned if you don’t use it in practice. I do have an interested in languages in general and love learning new language features and differences in how typing systems work and memory management. But it can be very dry for many people.

Does someone want to tell Theo that hooks are not functional programming, and React is very OOP? Just because a component doesn't have the keyword class, doesn't mean it's not essentially a class. A component function is a constructor, and props are the constructor args. And with regards to composition, whether your dependencies are declared as imports or injected into a constructor, it's all the same shit.

the description: "Theo Browne is a notorious tech RU-vidr and streamer" I feel like notorious is not the right word lol

Take away: the language doesn't matter much. The economy sucks.

Literally the most useless argument i ever heard

function overloading is a crime

Backend Banter? More like Backend Banger!

I also have the opposite going on. Got forced on to the elixir phoenix stack and feel miserable. What a god awful language and platform. Coming from kotlin & ts it feels like going back to the stone age
