How can I run asynchronously background task in V8?

[wHoIsDReAmer]

Does not it support?

like this

async function foo() {
    while (true) {
        // TODO SOME
        Thread.sleep(1000);
    }
}
foo();

// and can call another synchronous function
function test() {

}

// Java
// ... after call foo function

test.call(null, null);
// but above code is not work

I know that javenode comes out already, but is there no way?

Yes, you need to enable the V8 module. Project Javenode is a good example.

Then can't implement not only hand-made timer features but some background tasks? like expensive calculate (fibonacci) etc..

[caoccao]

The pattern is the same. The async capability is powered by Promise. That project demonstrates how to implement Promise.
