Unable to return value from async method in typescript

I am working on typescript.I am trying to return a value from the async method.However , it always returns {}. Below is what I coded.

    async returnNewUrlAfterClickingLink(): Promise<string> {
    const allHandles = await browser.getAllWindowHandles();
    await browser.switchTo().window(allHandles[2]);
    const cur_url = await browser.getCurrentUrl();
    console.log("url is" + cur_url);
    return cur_url;
}

However I am able to log the url correctly.

Your returnNewUrlAfterClickingLink is marked as async, so it always return promise now. In order to get this value, you need to await result of this function:

const url = await returnNewUrlAfterClickingLink()
console.log(url)

And again - to use await your function must be set async, so whole call stack must be async/await.

Hope this helps
