// Function returns a Promise<string> async function fetchData(): Promise<string> { // In a real scenario, we would actually fetch from an API // This is a mock implementation for demonstration return new Promise((resolve) => { setTimeout(() => { resolve("Response from server"); }, 1000); }); } // Using the async function async function displayData() { try { console.log("Fetching data..."); const data = await fetchData(); // TypeScript knows 'data' is a string console.log("Data length:", data.length); console.log("Data:", data); } catch (error) { console.error('An error occurred:', error); } } // Call the async function displayData();
