Promises & async: turning callbacks into linear code
FiveM is full of callback APIs: PerformHttpRequest, the older async MySQL libraries, NUI callbacks. Stack three of them and your code turns into a pyramid, each result trapped one level deeper than the last. Promises flatten the pyramid. Combined with Citizen.Await, you get top-to-bottom code that feels synchronous while the server stays free to do other work. This lesson builds the real thing: you wrap PerformHttpRequest in a promise, await it, handle failure with :reject(), and chain three calls in a straight line.

Make the resource folder
Inside your server's resources folder, create this folder:
resources/qu_promises
