FastScript vs. MRTK-Unity vs. PascalABC.NET vs. Racket Comparison Chart

MRTK-Unity is a Microsoft-driven project that provides a set of components and features, used to accelerate cross-platform MR app development in Unity. Provides the cross-platform input system and building blocks for spatial interactions and UI. Enables rapid prototyping via in-editor simulation that allows you to see changes immediately. Operates as an extensible framework that provides developers the ability to swap out core components. A button control that supports various input methods, including HoloLens 2's articulated hand. Standard UI for manipulating objects in 3D space. Script for manipulating objects with one or two hands. 2D style plane which supports scrolling with articulated hand input. A script for making objects interactable with visual states and theme support. Various object positioning behaviors such as tag-along, body-lock, constant view size, and surface magnetism. Script for laying out an array of objects in a three-dimensional shape.

Racket is a general-purpose, multi-paradigm programming language that serves as a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation, enabling developers to create new domain-specific and general-purpose languages. Racket's core language includes features such as macros, modules, lexical closures, tail calls, delimited continuations, parameters (fluid variables), software contracts, green threads, and OS threads. The language also comes with primitives, such as event spaces and custodians, which control resource management and enable the language to act like an operating system for loading and managing other programs. Further extensions to the language are created with the powerful macro system, which, together with the module system and custom parsers, can control all aspects of a language. Most language constructs in Racket are implemented as macros in the base language.
