Chapter 3: The simplest composite types of F , tuples and records, are introduced. They allow several values to be grouped together into one component. Furthermore, tagged values are introduced.

F Sharp (programming language)

Standard recursions on lists are studied and examples illustrating a model-based approach to functional program- ming are given. Chapter 5: The concepts of sets and maps are introduced and the powerful F collection libraries for lists, sets and maps are studied and applied in connection with a model-based approach.

Chapter 6: The concept of finite tree is introduced and illustrated through a broad selection of examples. Chapter 7: It is shown how users can make their own libraries by means of modules consisting of signature and implementation files. Furthermore, object-oriented features of F are mentioned. Chapter 8: Imperative features of F are introduced, including the array part of the col- lection library and the imperative sets and maps from the.

NET framework. Chapter 9: The memory management concepts, stack, heap and garbage collection, are described.

Tail-recursive functions are introduced and two techniques for deriving such functions are presented: one using accumulating parameters, the other continuations. Their efficiency advantages are illustrated. Chapter A variety of facilities for processing text are introduced, including regular expressions, file operations, web-based operations and culture-dependent string ordering.

The facilities are illustrated using a real-world example. Chapter A sequence is a, possibly infinite, collection of elements that are computed on-demand only. This is in sharp contrast to imperative programming, where the equivalent if construct is a statement, and producing values is often done with mutating variables.

In functional programming, it is rare to mutate values with statements. Although some functional languages support statements and mutation, it is not common to use these concepts in functional programming.

Pure functions As previously mentioned, pure functions are functions that: Always evaluate to the same value for the same input. Have no side effects. It is helpful to think of mathematical functions in this context. In mathematics, functions depend only on their arguments and do not have any side effects.

Pure functions in functional programming are the same way.

Introduction to Functional Programming in F#

When writing a pure function, the function must depend only on its arguments and not perform any action that results in a side effect. This pattern of depending on a global value is to be avoided in functional programming.

Although there is nothing inherently wrong with doing this, it does mean that the function is not pure. If another part of your program depends on something external to the program, such as the output buffer, then calling this function can affect that other part of your program.

Calling this function any number of times produces the same result: it just produces a value. The predictability given by purity is something many functional programmers strive for. Immutability Finally, one of the most fundamental concepts of typed functional programming is immutability.

In F , all values are immutable by default. That means they cannot be mutated in-place unless you explicitly mark them as mutable.

Learning F#

In practice, working with immutable values means that you change your approach to programming from, "I need to change something", to "I need to produce a new value". Some functional programming languages do not support mutation at all. In F , it is supported, but it is not the default behavior for values. This concept extends even further to data structures.No Easy Day: Standard recursions on lists are studied and examples illustrating a model-based approach to functional program- ming are given.
