How do I handle promises in TypeScript?

In TypeScript, you can handle promises using the Promise object. You can create a promise using the new Promise constructor.

Can you show me an example of creating a promise?

Sure! Here's a simple example:

const myPromise = new Promise((resolve, reject) => {
    const success = true;
    if (success) {
        resolve('Promise resolved!');
    } else {
        reject('Promise rejected!');
    }
});

How do I use .then() and .catch() with promises?

You can chain .then() and .catch() to handle the resolved and rejected states of the promise:

myPromise
    .then(result => console.log(result))
    .catch(error => console.error(error));

What about using async/await for promises?

Using async/await makes your code cleaner. You can use it like this:

async function handlePromise() {
    try {
        const result = await myPromise;
        console.log(result);
    } catch (error) {
        console.error(error);
    }
}
handlePromise();
