trigger — this will error
trigger — this will error
// Triggers TS2773 // Did you forget to use 'await'?
expected output
error TS2773: Did you forget to use 'await'?
Fix
Add 'async' to the containing function
WHEN Using await outside an async function
Add 'async' to the containing function
// Mark the function as async
async function fetchData() {
const result = await fetch('/api/data');
return result.json();
}Why this works
await can only be used inside async functions; the 'async' keyword makes the function return a Promise.
