promise.then returns a promise, so that we can call the next .then on it..then(handler) may create and return a promise. In that case further handlers wait until it settles, and then get its result..then (or catch/finally, doesn’t matter) handler returns a promise, the rest of the chain waits until it settles. When it does, its result (or error) is passed further.1
