- Racket supports keyword arguments for functions, making it easier to understand arguments.
- The match form in Racket allows unpacking and analyzing data using patterns.
- Racket's struct is used for defining custom data structures with constructors, accessors, and predicates.
- Racket allows declaring modules in the language to group and isolate code.
- Racket supports mutable structs by adding the #:mutable flag.
