In computer science, declarative programming is a programming paradigm—a style of building the structure and elements of computer programs—that expresses the logic of a computation without describing its control flow. This is how the above program would be implemented using a declarative style:
2016-11-13 · It’s important to note that I’m not saying that declarative programming is inherently slower than imperative programming though. Declarative languages can actually be much faster and more efficient with resources believe it or not.

In declarative programming, typical programming constructs such as loops and if/then conditions do not exist, because they are instructional. Declarative programming focuses on the end result, while imperative programming focuses on how to get there. For example, when you jump in a taxi, you declare to the driver where you want to go.
They can also express an opinion. She leaves for college tomorrow morning; the house is going to feel empty without her. A great example of a declarative abstraction is d3.js. D3 is a library that helps you build interactive and animated visualisations of data using JavaScript and (typically) SVG. The first time (and fifth time, and possibly even the tenth time) you see or try and write d3 code your head will hurt.
