Return a value from an asynchronous function call
David Y.
—How to access a return value from an asynchronous function call in JavaScript?
In modern JavaScript, we can use await when calling asynchronous functions to pause the execution of the current function until a value is returned. This allows us to write and reason about asynchronous code as if it were synchronous.
The code below provides an example:
async function asyncHelloWorld() { return "Hello world!"; } async function asyncCaller() { const result = await asyncHelloWorld(); console.log(result); // will print "Hello world!" } asyncCaller();
Note that await can only be called from within asynchronous functions or top-level code inside a module.
