Advanced JavaScript

What is Advanced JavaScript?

Advanced JavaScript includes concepts like closures, promises, async/await, and ES6+ features. These are essential for building modern web applications.

Example: Using Promises

const fetchData = () => {
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve("Data fetched successfully!");
        }, 2000);
    });
};

fetchData().then(response => {
    console.log(response);
});
        

Example: Async/Await

const fetchData = async () => {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    console.log(data);
};

fetchData();
