A Game of Theories: Why languages do what they do
summary
Claims and concrete mechanics: Ruby favors flexibility and monkey‑patching and uses array size jumps (examples: initial capacity 3 then 20 then 37) to avoid reallocs; Python follows the Zen and prefers dictionary lookups over adding a case/switch; Go uses goroutines and channels for concurrency, keeps true arrays and slices and intentionally omits generics; Rust enforces ownership/Option instead of null and uses ownership for deterministic deallocation; Erlang isolates processes and restarts failures; Clojure gives immutable data on the JVM; JavaScript is malformed for browsers (written in ten days) and relies on === for safety.
