Async JavaScript Evolution
JavaScript's async capabilities have evolved significantly. Understanding them is crucial for modern web development.
Promises
fetch(url)\n .then(res => res.json())\n .then(data => console.log(data))Async/Await
const response = await fetch(url);\nconst data = await response.json();Async/await makes async code look and behave more like synchronous code, improving readability.
Error Handling
Always handle errors in async code. Use try/catch with async/await.
