Basics
Question | Answer |
---|---|
What is the meaning of the dollar sign "$"? | "$" is a way to avoid typing too many brackets.
For example: foo x = h (g (f x))
is the same as foo x = h $ g $ f x
|
What is point-free style? | Point-free style is a way to define functions solely as a composition of other functions, leaving arguments in the definition out.
For example: takeFive x = take 5 x
is the same as takeFive = take 5
in point-free style. |
What is the meaning of the dot "."? | "." is used to compose functions in point-free style, similar to "$".
For example: foo x = h $ g $ f x
is the same as foo = h . g . f
