stepwise development

Stepwise development is a programming methodology where a system is built incrementally through a series of small, well-defined steps. On WindowsForum.com, this concept is illustrated in the context of functional programming, specifically through the development of an interpreter for a simple functional language. The process involves evolving the interpreter by adding features such as Booleans, natural numbers, lambdas, and recursive lets in a stepwise manner. This approach helps in understanding important functional programming techniques and programming language theory. The tag covers discussions around incremental development, interpreter construction, and functional programming principles as applied to language design.
