How to implement delay function in V8 mode?

See original GitHub issue

delay is different from sleep , delay will not block js ui thread but only stop a while and prevent processing the next line of code. It is possible to execute js or get callback when delaying. Is there any api to hangup v8 to implement delay function in V8 mode?

I’ve found sth.Thanks.

v8ValuePromiseResolver = getEventLoop().getV8Runtime().createV8ValuePromise();
if (recurrent) {
    timerId = getEventLoop().getVertx().setPeriodic(delay, id -> {
        if (!isClosed()) {
            if (resolve) {
                try {
                } catch (Throwable t) {
                    getLogger().logError(t, "Failed to resolve the promise.");
            } else {
                try {
                } catch (Throwable t) {
                    getLogger().logError(t, "Failed to reject the promise.");

That question belongs to TC39, I think.
