Why don't you need a semicolon with fetch() and JavaScript promises?

Hi Liz.

Sometimes in JavaScript you can chain function calls if the previous function call returns another function.

When you execute fetch function, it returns an object that has a few methods on it, including the method then and the method catch. In this case, you execute the fetch function, it returns an object with the then property on it so you "chain" it. The thenmethod also returns an object with the then and catch methods on it so you can chain then again and you can keep doing it as many times as you want (because the previous then method will always return a new object with the methods then and catch that you can continue chaining...

This would work too

const promise = fetch('https://dog.ceo/api/breeds/image/random'); // an object with the method then and catch (a few more too) is returned from this function call

promise
.then(response => response.json())
.then(data => console.log(data.message))

Let me know if I didn't make myself clear
