How do I use promises in Angular?

In Angular, you can use promises to handle asynchronous operations. You can create a promise using the Promise constructor.

Can you show me an example of creating a promise?

Sure! Here's a simple example:

let myPromise = new Promise((resolve, reject) => {
    // Simulate an async operation
    setTimeout(() => {
        resolve('Operation successful!');
    }, 2000);
});

myPromise.then(result => {
    console.log(result);
});

How do I handle errors with promises?

You can handle errors using the .catch() method. For example:

myPromise
    .then(result => console.log(result))
    .catch(error => console.error('Error:', error));

What about using async/await with promises?

You can use async/await for a cleaner syntax. Just mark your function as async and use await before the promise:

async function asyncFunction() {
    try {
        const result = await myPromise;
        console.log(result);
    } catch (error) {
        console.error('Error:', error);
    }
}
