Functional programming languages such as Haskell, Scheme, and ML evaluate expressions via Hybrid languages. Makefiles, for example, Declarative programming example One of the strengths of declarative programming is its ability to describe problems more briefly and succinctly than imperative languages. If we want to output a list of first names, in PHP this can be described with just one line of code using declarative programming – as the example shows – while the imperative method requires five lines. A more modern example of declarative programming is the Model-View-Update pattern for UI. In this pattern, the View is the declarative part that says what the behaviors and UI should look like, and it’s separate from the Model (the data). Examples of Declarative Programming Languages.
