## Usage
|

|
||||
```js
|
||||
import compose from 'cumpa'
|
||||
|
||||
const add2 = x => x + 2
|
||||
const multiplyBy3 = x => x * 3
|
||||
|
||||
const add2AndMultiplyBy3 = compose(multiplyBy3, add2)
|
||||
|
||||
console.log(add2AndMultiplyBy3(1)) // ((1 + 2) * 3) = 9
|
||||

### composeRight
|
||||
|
||||
Similar to compose but performs from left-to-right function composition.<br/>
|
||||
[see also](https://30secondsofcode.org/function#composeright)
|
||||
|
||||
#### Parameters
|
||||
|
||||
- `fns` **...\[[function](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Statements/function)]** ) - list of unary fynctions
|
||||
|
||||
Returns **any** result of the computation
|
||||
|
||||
### compose
|
||||
|
||||
Performs right-to-left function composition.
|
||||
Use Array.prototype.reduce() to perform right-to-left function composition.
|
||||
The last (rightmost) function can accept one or more arguments; the remaining functions must be unary.<br/>
|
||||
