Embedded languages are programming languages that are integrated within another programming environment or language. They allow developers to write code that can be executed within a host application, enhancing its functionality. For example, a web page might use an embedded language like JavaScript to create interactive features. These languages often provide specific features tailored to the host environment, making them easier to use for particular tasks. An example is SQL, which is embedded in applications to manage and query databases. This integration helps streamline development by allowing developers to leverage the strengths of both the host and embedded languages.
