Although it is technically possible to use Qt Quick by writing C++ code, the module is accompanied by a dedicated programming language called QML (Qt Modeling Language). QML is an easy to read and understand declarative language that describes the world as a hierarchy of components that interact and relate to one another. It uses a JSON-like syntax and allows us to use imperative JavaScript expressions as well as dynamic property bindings. So, what is a declarative language, anyway?
Declarative programming is one of the programming paradigms that dictates that the program describes the logic of the computation without specifying how this result should be obtained. In contrast to imperative programming, where the logic is expressed as a list of explicit steps forming an algorithm that directly modifies the intermediate program state, a declarative approach...
