Deep dives
Definition of Domain-Specific Languages
Domain-specific languages (DSLs) are computer programming languages of limited expressiveness focused on a particular domain. They are language-like in nature, with defined syntax and semantics. DSLs are executable by computers and are used for specific parts of a system, focusing on a specific domain. The syntax of a DSL is designed to make sense within the construct of the domain, and the language expresses concepts and behaviors of that domain.
