Declarative programming: telling the “machine”1whatyou would like to happen, and let the computer figure outhowto do it. 1Computer/database/programming language/etc Examples of imperative and declarative codeLink to this section Taking a simple example, let’s say we wish to double all the ...
The idea of imperative programming goes way back to 1950s, which is when the first high-level programming languages have been created. With 72 vacuum tube transistors and 18K of memory at disposal, the programs must have been as performant as possible. The only way to achieve it was to wri...

The think of giving driving directions is a simplified example to differentiate between a declarative and imperative approach. A declarative approach gives the address of how to arrive at a given destination without a thought about how it is found, whereas an imperative approach offers step-by-step...
Declarative programming (also known as functional programming) languages do not attempt to control the flow of a program; they establish desired results i.e. specifying what they want to happen but not how it should happen. HTML is an example of declarative programming because it does not attemp...

F# also has other constructs that support imperative programming. You've already seen some in Chapter 3. Any example that wrote to the console included a few lines of imperative code alongside functional code. In this chapter, you'll explore these constructs, and many others, in much more ...
Although most languages were designed to support a specific programming paradigm, many general languages are flexible enough to support multiple paradigms. For example, most languages that contain function pointers can be used to credibly support functional programming. Furthermore, C# and Visual Basic ...
