1.5 Implementations🔗ℹ

The definition of Racket aims for determinism and independence from its implementation. Nevertheless, some details inevitably vary with the implementation. Racket currently has two main implementations:

Most Racket programs run the same in all implementation variants, but some Racket features are available only on some implementation variants, and the interaction of Racket and foreign functions is significantly different across the variants. Use system-type to get information about the current running implementation.
