Running Programs in a Forever Loop with Effect and Fork

import { Effect } from "effect";

const FirstThread = Effect.forever(
  Effect.gen(function* () {
    yield* Effect.log("First thread").pipe(Effect.delay("10 millis"));
  })
);

const SecondThread = Effect.forever(
  Effect.gen(function* () {
    yield* Effect.log("Second thread").pipe(Effect.delay("10 millis"));
  })
);

const program = Effect.all([
  Effect.fork(FirstThread),
  Effect.fork(SecondThread),
  Effect.never
]);
