## F#
|
|||
|
|
|
|||
|
|
F# is a strongly typed language that inherit from the object oriented language (C#) but encourage a functional programmation. It runs on the .NET CLR, and can seamlessly inter-operate with C#.
|
|||
|
|
It is compatible with visual studio and is officialy supported by Microsoft.
|
|||
|
|
|

|
|
#### Immutability
|
|||
|
|
|
|||
|
|
Variables in F# are by default immutable. That means that their values can't be changed after initialization. Mutability can be forced by the keyword "mut". One of the F# best practices is to just make a copy of the variable you want and change the values you need at the initialization of the newly created variable
|
|||
|
|
|
|||
|
|
#### Records
|
|||
|
|
|
|||
|
|
F# can use objects but it is encouraged to use instead Records. Records are a set of members, and can be seens as structs for people that comes from a C background.
|
|||
|
|
|
|||
|
|
For example :
|
|||
|
|
|
|||
|
|
<code>
|
|||
|
|
type People = {
|
|||
|
|
Age: int
|
|||
|
|
FirstName: string
|
|||
|
|
LastName: string
|
|||
|
|
}
|
|||
|
|
</code>
