Flow has a concept of "opaque types", pretty similar to what the branded types pattern in TypeScript aims to solve Really recommend reading this article: codemix.com/opaque-types-in-… Will record a video tomorrow about it 😄

Type predicates are super useful for narrowing down types based on conditionals Especially on cases where you receive unknown raw values and have to validate those - branded types can also come into play here However, it's possible to easily introduce bugs, cause the TS compiler won't notice in case the runtime logic doesn't match the predicate👇

Here's a quick explanation of how to use tuples and conditional types to define dynamic arguments in TypeScript 🎥

Going to schedule it for tomorrow, cause I've just finished editing it! But here's a snippet:

Will try to ship a new video style today, using animated code snippets 🎥

Chill day, learning some Ruby and also trying to build a small app with Rails 7.0

3 ways to use Mapped Types in TypeScript 👇 - From union to object - From object to union - Key remapping via "as"

Getting back to Ruby code after getting used to Elixir, trying to write a method and then ending up with "do" at the end 🥲

My teammate and I just ended up fighting with Ruby for like 1 hour in order to manage a fix related to bundle install with Sorbet 😵‍💫

What's "as const" in TypeScript and what are the use cases for that? Let's take a quick look into it 👇

Going to continue posting updates regarding the Elixir SDK 👀 I'm essentially taking it as a side project, setting the goal of releasing an official version of it Last week I raised a lot of PRs, mainly refactoring the main modules, and now I just need to polish those and ship 🚢
