The VM used for the online REPL is the [Javascript implementation](../docs/bqn.js), while [CBQN](https://github.com/dzaima/CBQN) is a more advanced VM in C. There are platform-specific and generic tests in the [test](../test/) directory. -The VM used for the online REPL is the [Javascript implementation](../docs/bqn.js). The bytecode matches dzaima/BQN's format, and [an extension](../dc.bqn) to the compiler adjusts the slightly different block declarations to target dzaima+reference BQN. [An earlier experiment](../wc.bqn) targetting [WebAssembly](https://en.wikipedia.org/wiki/WebAssembly) works only on a very small subset of BQN.
