 ## Variables
 
 | Variable | Description |
 | ------ | ------ |
 | [compose](variables/compose.md) | Composes two functions, `ab` and `bc` into a single function that takes in an argument `a` of type `A` and returns a result of type `C`. The result is obtained by first applying the `ab` function to `a` and then applying the `bc` function to the result of `ab`. |
 | [dual](variables/dual.md) | Creates a function that can be used in a data-last (aka `pipe`able) or data-first style. |
