A Domain-Specific Language (DSL) is a programming language designed to solve problems in a specific domain or area of interest. Unlike general-purpose languages like Python or Java, which can be used for a wide range of applications, DSLs are tailored to particular tasks, making them more efficient and easier to use for those specific purposes. Examples include SQL for database queries and HTML for web page structure. DSLs can enhance productivity by providing specialized syntax and features that align closely with the needs of the domain. This allows developers and domain experts to communicate more effectively and reduces the complexity of coding tasks. By focusing on a narrow scope, DSLs can streamline development processes and improve code readability.
