Editing Parrot virtual machine (section)

===Static and dynamic languages===
The differing properties of [[Type checking|statically and dynamically typed]] languages motivated the design of Parrot. Current popular virtual machines such as the [[Java virtual machine]] and the [[Common Language Runtime]] (for the [[.NET]] platform) have been designed for statically typed languages, while the languages targeted by Parrot are dynamically typed.

Virtual machines such as the Java virtual machine and the current Perl 5 virtual machine are also [[Stack machine|stack-based]]. Parrot developers chose a register-based design, reasoning that it more closely resembles a hardware design, allowing the vast literature on [[compiler optimization]] to be used in generating bytecode for the Parrot virtual machine that could run at speeds closer to [[machine code]].{{cn|date=November 2023}} Other register-based virtual machines inspired parts of Parrot's design, including [[LLVM]], the [[Lua (programming language)#Internals|Lua VM]] and Inferno's [[Dis virtual machine|Dis]].
