Embedded Domain-Specific Languages (EDSLs) is a software development approach that involves creating mini-languages to solve specific problems within a particular domain. These languages are tailored to meet the unique needs and requirements of a specific application, and they often provide a more concise and readable syntax for developers to follow. EDSLs are typically embedded within an existing programming language, making it possible to create custom-built solutions that integrate more seamlessly with the existing codebase. This specialized skill requires an in-depth knowledge of programming languages and the ability to design and implement EDSLs that align with the goals of the project.
