What is an example of a declarative code?
Declarative code focuses on expressions that are saying what without adding how. For example, HTML code <img src=”./turtle. jpg” /> tells the browser to display an image of a turtle without telling the browser how. It is also typical that a declarative code avoids mutation of state and variables.
What is a declarative model?
Declarative models rely on preconfigured capabilities in the language to accomplish a task without explicit case-by-case instructions on what steps to take.
What is difference between imperative and declarative?
Declarative sentences are those that emphasize a statement of fact, while imperative sentences provide instructions or commands. Learn how to differentiate and use these two types of sentences.

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 the query interpreter of the database system to design and perform a computational process to produce such a result.

Evidently, Angular lets programmer to follow imperative approach while react encourages declarative approach. The “separation of concern” goes pretty well with declarative approach here, while the same can be achieved with Angular by wiring things together in more manual way(using Angular's service).
Is SAS a declarative language?
As with SQL, SAS is primarily a declarative rather than imperative language. In other words, you tell SAS what you wish to accomplish and let the program figure out how to accomplish it. Another feature of SAS is that it is designed to work with data on disk rather than in RAM, unlike R or Stata.
