Domain-specific languages trade generality for expressiveness

A DSL is a small language optimized for a specific problem domain. SQL for queries, regex for patterns, CSS for styling.

The bargain: you give up Turing completeness (usually) and get clarity, safety, and domain-native abstractions in return.

Internal DSLs embed in host languages (fluent APIs, Ruby blocks). External DSLs have their own syntax and parser.

Building DSLs is easier now—tools like langium handle grammar, parsing, and editor integration.
