Gradual typing is a type system that allows for both static typing and dynamic typing but enforces types at runtime, and it lets software developers choose either type paradigm as appropriate from within a single language. The cited article says that in many cases gradual typing is added to an existing dynamic language, creating a derived language that allows, but does not require, static typing, while in some cases a language uses gradual typing from the start. It adds that there are performance and implementation complexity tradeoffs compared to dynamic or optional typing. Languages the atlas records as gradually typed are grouped under this entry.
