Declarative programming focuses on the end result, while imperative programming focuses on how to get there. For example, when you jump in a taxi, youdeclareto the driver where you want to go. You don't tell him how to get there by providing turn-by-turn directions. The turn-by-turn d...
Declarative code is aprogramming paradigmthat focuses on describingwhatthe program should accomplish rather thanhowit should be done. What Is Meant by Declarative Code? Declarative code is a style of programming where the developer expresses the logic of computation without explicitly specifying the cont...
See also:Multi-paradigm programming language Makefiles, for example, specify dependencies in a declarative fashion,[5]but include an imperative list of actions to take as well. Similarly,yaccspecifies a context free grammar declaratively, but includes code snippets from a host language, which is u...
We’re all used to the imperative paradigm. It’s what all of us have been taught while learning to code, and that’s the main reason why this age-old style is still dominant in modern programming languages. However, as software projects become more and more complex, it is more important...
UsingObjectAnimatoris an example of Declarative Programming: I used a preexisting framework’s API to specify WHAT I want to happen and left it up to the framework to figure out the details. Clearly, in this case, Declarative approach is the better choice. ...
Declarative programmingReading the React documentation or blog posts about React, you have undoubtedly come across the term declarative. One of the reasons why React is so powerful is because it enforces a declarative programming paradigm.Consequently, to master React, it is essential to understand ...
SQL is an example of a declarative programming language. Statements do not describe computations directly, but instead describe the desired result of some computation. It is the role of thequery interpreterof the database system to design and perform a computational process to produce such a result...
In the following two sections, I will present the two main problems of declarative programming:separatenessandlack of unfolding. Every critique needs its bogeyman, so I will use HTML templating systems as a concrete example of the shortcomings of declarative programming. ...

The idea behind reactive programming is that everything can be represented as a sequence. Let us consider another example - a network request.---[Response]---> The outcome of a network request is a response. Although we have only one response, we can still think of it as a sequence. ...
