While writing async code can indeed be challenging, I just disagree with the idea that JavaScript is lacking good "locking primitives": > All this async code without decent locking primitives is leading to a rabbit hole of race conditions... No, it's not. Here's a lock: let lock = Promise.resolve() // ... lock = lock.then(() => { /* critical section */ }) For the rare instances where more complex async flow control is required, there are a bunch of libraries for that (e.g. async[0], p-queue[1], etc.).
