I believe async/await uses promises behind the scenes. It just means invoking code looks nicer, i.e writing "var res1 = await prom1(a); await prom2(a, res1)" is marginally cleaner than "return prom1(a).then((res1) => prom2(a, res1));", in the sense that you're just writing statements rather than chaining method invocations.
