Future.wait and Parallel Work
Run multiple futures concurrently.
Awaiting One by One Is Slow
Awaiting futures in sequence makes each one wait for the last. Three one-second calls then take three seconds total.
Start Them Together
Kick off independent async calls first, then await them. They run concurrently, so total time tracks the slowest, not the sum.
