const compose = (...functions) => args => functions.reduceRight((arg, fn) => fn(arg), args);

// Example:
// const league = [
//  { heroe: "superman", power: 'fly' },
//  { heroe: "batman", power: 'millionare'},
//  { heroe: "flash", power: 'speed' },
//]
//const filter = f => arr => arr.filter(f);
//const map = m => arr => arr.map(m);
//let res = compose(
//  map(h => h.heroe),
//  filter(h => h.power === 'fly')
//)(league); // ["superman"]
