How to chain a promise in JavaScript?
To chain promises, we use the then method, which takes a callback function as its parameter. The callback function receives the resolved value of the previous promise as its argument. Inside the callback function, we can return a new promise to continue the chain. Here's an example that demonstrates promise chaining:

The getUser function returns a promise that resolves with a user object, and the getUserPosts function returns a promise that resolves with an array of user posts. We chain the promises together using the then method. The resolved value of the previous promise (user) is passed as the argument to the next then callback function.
