Handling Asynchronous Operations
JavaScript is single-threaded with an event loop. Network requests, timers, and file operations execute asynchronously to prevent freezing the user interface.
Async / Await Syntax
Async/await provides clean, synchronous-looking code for managing Promises without callback nesting.
javascript Example
// Fetching course data asynchronously
async function loadCourseData(slug) {
try {
const response = await fetch(`/api/course/${slug}`);
if (!response.ok) throw new Error("Course not found");
const data = await response.json();
console.log("Course loaded:", data.title);
return data;
} catch (error) {
console.error("Fetch failed:", error.message);
}
}
