JavaScript Prime Number Generator

PrimeGenerator.js

function* nats(n) {
  yield n
  yield* nats(n + 1)
}

function* sieve(gen) {
  const n = gen.next().value
  yield n

  yield* sieve((function* () {
    for (const i of gen) {
      if (i % n !== 0) {
        yield i
      }
    }
  })())
}

const prime = sieve(nats(2))

console.log(prime.next().value) // 2
console.log(prime.next().value) // 3
console.log(prime.next().value) // 5
console.log(prime.next().value) // 7
console.log(prime.next().value) // 11
