Call async from non-async
We have a “regular” function called f. How can you call the async function wait() and use its result inside of f?
async function wait() { await new Promise(resolve => setTimeout(resolve, 1000)); return 10; } function f() { // ...what should you write here? // we need to call async wait() and wait to get 10 // remember, we can't use "await" }P.S. The task is technically very simple, but the question is quite common for developers new to async/await.
That’s the case when knowing how it works inside is helpful.
Just treat async call as promise and attach .then to it:
async function wait() { await new Promise(resolve => setTimeout(resolve, 1000)); return 10; } function f() { // shows 10 after 1 second wait().then(result => alert(result)); } f();
