Syntax
| 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 another way to define TODO |
| What is the meaning of the dot "."? | "." is used in point-free style code similar to "$".
For example: foo x = h $ g $ f x
is the same as foo = h . g . f
