Variables and Types in Perl
Perl’s approach to variables is unique among programming languages. Instead of declaring a type, you prefix each variable with a sigil—a symbol that tells Perl (and you) what kind of data …

Variables and Types in Pascal
Pascal’s type system was one of its most influential contributions to programming language design. Niklaus Wirth designed Pascal with strong, static typing to catch errors at compile time rather …
Read more →Variables and Types in Odin
Odin is statically and strongly typed — every variable has a fixed type determined at compile time. Odin’s declaration syntax reads left-to-right: name : type = value for variables, name :: …
Variables and Types in OCaml
In most languages, variables are mutable containers that hold values. OCaml takes a different approach. With its roots in the ML family of functional languages, OCaml uses let bindings — names bound …
Read more →Variables and Types in Nim
Nim’s type system is one of its defining features — statically typed and strongly checked at compile time, yet remarkably ergonomic thanks to powerful type inference. Where languages like Python …
Read more →Variables and Types in MUMPS
MUMPS takes a radically different approach to variables and types compared to most programming languages. There are no type declarations, no type keywords, and no distinction between strings and …
Read more →Variables and Types in Mojo
Mojo’s type system is one of its most distinctive features. As a Python superset, Mojo supports both dynamic typing (Python-style) and static typing (systems-style) in the same language. This …
Read more →Variables and Types in Modula-2
Modula-2’s type system is one of its defining features. Designed by Niklaus Wirth as an improvement over Pascal, Modula-2 enforces strict, static typing that catches errors at compile time …
Read more →Variables and Types in MATLAB
MATLAB’s type system reflects its origins as a matrix laboratory. Every value is fundamentally an array—a scalar is a 1x1 matrix, a string is a 1xN character array, and even a boolean is a 1x1 …
Read more →Variables and Types in Lua
Lua takes a minimalist approach to its type system. With only eight basic types and no type declarations required, Lua lets you focus on solving problems rather than satisfying a compiler. Variables …
