From Python and JavaScript to COBOL and BQN. Each language has its own page with versions, sample code, and a one-click way into the playground.
The languages every hiring pipeline asks about. Real compilers, latest versions.
Native compilation, low-level primitives, real syscalls.
Immutable-first, algebraic types, expression-oriented.
One-file glue, text processing, ops-side jobs.
Matrix math, arbitrary precision, HPC.
Real servers (PostgreSQL, MariaDB, Redis) and embedded engines (SQLite, DuckDB) in a Firecracker VM. Sample schema pre-loaded; writes vanish on exit.
Educational, historic, or purely-for-fun — but real compilers.
