Racket is a popular variant of the Scheme programming language. Its features and benefits include:

• Grow your Program: Racket's interactive mode encourages experimentation, and quick scripts easily compose into larger systems. Small scripts and large systems both benefit from native-code JIT compilation. When a system gets too big to keep in your head, you can add static types.
• Grow your Language: Extend Racket whenever you need to. Mold it to better suit your tasks without sacrificing interoperability with existing libraries and without having to modify the tool chain. When less is more, you can remove parts of a language or start over and build a new one.
• Grow your Skills: Whether you're just starting out, want to know more about programming language applications or models, looking to expand your horizons, or ready to dive into research, Racket can help you become a better programmer and system builder.

v6.10版本新功能

Version 6.10:

• Internally, Racket’s intermediate compatibility layer over operating-system facilities has been moved into its own library, 'rktio', so it can be used in future Racket implementations. This change should be transparent, but the refactoring moves code that has many compiler and OS dependencies, so we expect a new glitch or two in less-common build and execution environments. Please report problems at https://github.com/racket/racket/issues.
• Racket supports cross-compilation of executables in more cases, including executables that depend on packages for foreign libraries.
• The struct form supports an #:authentic annotation to declare that chaperones and impersonators are never allowed on instances of the declared structure type. This annotation is intended for use on a library’s internal data structures, where it won’t interfere with contracts or other forms of extension at a library’s interface. It can sometimes provide a small performance boost.
• RackUnit adds nested-info and string-info to grant custom checks more control over the display and layout of check failure info.
• The raco test command provides the ++arg and ++args flags to pass arguments to tested programs.
• Typed Racket has types for immutable, mutable, and weak hashtables; in other words the type (HashTable K V) is a union (U (Immutable-HashTable K V) (Mutable-HashTable K V) (Weak-HashTable K V)). Standard library functions may have more specific return types. For example, hash-set has type (-> (HashTable K V) K V (Immutable-HashTable K V)). When an immutable hashtable flows from untyped code to typed code, Typed Racket may use a flat contract to verify its type (provided the table’s key and value types are flat).
• The Typed Racket Optimizer is disabled in untrusted contexts (e.g., sandboxes). This prevents unsoundness in the Typed Racket type system from being used to get access to unsafe operations.
• Racket’s internal runtime adds a scheme_atexit procedure with identical behavior as atexit defined in libc.
