Challenge 1 / 1

There is no advantage in doing so. Promise.all() is just syntax sugar. It will make our code more readable and clean.

Promise.all() has the ability to launch both ajax calls in parallel. Once all calls are completed, the code will continue as normal.

Promise.all() lets you organize your ajax calls in a way so that one call executes right after the other. This way, your data from the previous call is already available by the time you call the next one, which can be useful!

While Promise.all() won't give you any significant advantage, it's in general a little bit faster than the async keyword. for reasons of micro-optimizations.
