Js Throw Error From Async Function. Note that the value assignment works only when a promise functions resolves. Throw error if the promise function rejects anything. Suppose you have an async function run(). We can use try.catch (in combination with async functions) and the.catch() approaches to handle errors for asynchronous code.
