When the callback function delivers a promise, promise chaining occurs. It allows you to chain on another promise and then conduct a function when the second promise is completed. Catch can still be used to deal with any problems that arise along the process.

It's a non-blocking, asynchronous language. Javascript does not run in parallel, but rather executes one function/Promise at a time.

Promises are the most straightforward way to handle asynchronous actions. They are more efficient than callbacks and events in handling multiple asynchronous operations and handling errors.
