Our Verdict

Asynchronous JavaScript: Promises, Callbacks, Async Await by Viktor is a fundamentals-focused course that offers clear explanations of essential concepts. While the audio quality can be inconsistent at times, with occasional accent challenges, its direct approach and engaging animations make it an effective learning resource for developers looking to understand advanced asynchronous operations in JavaScript. However, some may crave more real-world examples, a production-grade code walkthrough, or extra introduction to web development applications.
