import { either } from "https://deno.land/x/fae@v1.1.1/mod.ts";
A function wrapping calls to the two functions in an || operation,
returning the result of the first function if it is true and the result
of the second function otherwise. Second function will not be invoked if the first returns a
true value.
const gt10 = x => x > 10
const even = x => (x & 1) === 0
const f = Fae.either(gt10, even)
f(101) //=> true
f(8) //=> true
