Discussion on: All (or just most) of what you need to know about handling Promises

[Joel Ruiz]

You can chain the Promises. Inside of .then(), you can return another promise and it'll let you add another .then() underneath. You add a single .catch() at very end, which will work for all the .then() chains.

longPromise()
    .then((data)=>{
        console.log(data); // logs: longPromise resolved
        return shortPromise();
    .then((data)=>{
        console.log(data) // logs: shortPromise resolved
    })
    .catch((error)=> {
         console.log(error);
    })
});
