This is an experiment of solving https://projecteuler.net/ problems using Javascript. Code must work only in Chrome; so latest ES6 is allowed. These little programs make use of:

• generators
• spread operator
• destructuring assignment
• Set
• for... of
• arrow notation

function divisors(nb) {
  let res=new Set();
  for (let combi of combinations(primeFactors(nb)))
    res.add(combi.reduce((res,nb)=>res*nb, 1));
  return [...res];
}
