What's Next

You have completed the OCaml course. You can now write idiomatic OCaml — defining functions, using pattern matching, transforming lists, and modeling data with tuples and options.

Go Deeper

• Algebraic data types — define variants with data payloads and use exhaustive pattern matching.
• The module system — signatures, functors, and first-class modules for abstraction at scale.
• Imperative features — mutable references, arrays, for/while loops, and exceptions.
• The opam ecosystem — dune build system, lwt for async I/O, dream for web servers, cmdliner for CLI tools.
• OCaml 5 effects — algebraic effects and multicore parallelism.

Resources
