I'm a full-stack Rails dev and I have two glacially slow learning projects going on: an early-facebook clone to learn Elixir + Phoenix and a macOS timesheet app to learn Swift + SwiftUI. Both stacks are totally great and enjoyable btw, would recommend. When I first meet a language I usually crack open the docs and then write a single micro project, like a BFS maze solver or a knapsack problem solver or something Advent of Code-esque, just to get to know all the primitives quickly -- different kinds of variables, arrays, dicts, control flow, closures, error handling.
