How to send a message from worker to main script?

[NikitaMelikhov]

I mean somting like this in main script

worker.addEventListener("message", e => {
                console.log(e.data);
            }, false);

I know the promise style return value, but this style only return 1 value at at time. if I want to receive a series of values, like post message by setInterval() in worker context. how can I receive the messages sent by worker ?
