Function: compose()
Returns a function that takes a single parameter and pipes it through the given functions.
Example
import { compose, map, reduce, toArray } from 'lfi'
const screamify = compose(
map(word => word.toUpperCase()),
reduce(toArray()),
// Also works with non-`lfi` functions!
array => array.sort(),
)
console.log(screamify([`sloth`, `lazy`, `sleep`]))
//=> [ 'SLOTH', 'LAZY', 'SLEEP' ]
