Declarative programming often considers programs as theories of a formal logic.


It commonly includes regular expressions, logic programming, and functional
programming.


A declarative language describes what it wants to accomplish rather than focusing

Writing a declarative statements that show a relationship between each other.



Functional Programming is when functions, not objects or procedures, are

A scripting language is a form of programming language that is
usually interpreted rather than compiled.


Programs in scripting language are interpreted one command at a

Scripting languages are often written to facilitate enhanced
features of Web sites. These features are processed on the server
but the script in a specific page runs on the user’s browser.
