Ruby hash destructuring can feel as smooth as JavaScript: the rightward pattern matching syntax extracts values from a hash in one line, renames them, destructures arrays, groups elements, and rebuilds hashes afterwards. Practical examples for cleaner Ruby code.
sharding
Database sharding in Rails step by step: create a separate database per shard, wire them up in database.yml, and query across them. Plus how sharding differs from partitioning, with a native PostgreSQL partitioning example done through Rails migrations.

Ruby 3.2 runs in the browser through WebAssembly: embed Ruby in a script tag with ruby-wasm-wasi or drive the Ruby VM from JavaScript and mix it with HTML. Working examples plus honest limits: no threading or networking, and no extra gems without a custom wasm image.
Three ways to define constants and enums per class in Ruby: the ActiveRecord enum macro, a mixed style combining frozen constants with enum, and a dependency-free PORO version. Code for each solution and a comparison to help you pick the right one.
The Factory Pattern in Ruby, then a step further: using naming conventions and regular expressions so the factory auto-detects which notification class to instantiate. Complete code for both versions, plus when strict class listing is the safer choice.
Ruby 3.2 adds new syntax for anonymous arguments: forward positional and keyword arguments with bare * and ** and unpack them inside the method, no more digging through kwargs hashes. A before-and-after example shows how much cleaner argument passing gets.
