    I have to say, Joy's teaching style is completely off the charts. I loved the moment you picked up the keyboard to show where the back tick symbol is located. LOL. Best Javasript Callback, Promises and Async tutorial I have ever encountered. Someone give this man a medal

      You’re so right. These simple concepts are so hard to grasp when you are starting coding. Joy did a great job keeping them simple. Yeah he is very funny but I like his confidence in the whole time.

  • @CyberIllusions
    @CyberIllusions 2 года назад +68

    This is by far the best explanation I have seen so far. And I have to say that I have consumed many tutorials that leave you even more confused after the explanation because some things are just very abstract.
    Joy has an absolute talent for demystifying these abstractions and explaining them with simple real world analogies so that really EVERYONE can understand. So for JavaScript beginners, absolutely perfect and totally recommended!
    Someone once said: if you can't explain something in simple terms, you haven't really understood it yourself. Joy has proven that he understood it. I wish many would follow this example. Big thumbs up for this one!! 👍👍👌👌

    For a beginner web developer, at the start it's really very hard to understand the async n await functionality, after watching a bundle of videos multiple times, I used to forget this concept very frequently. But the way you explained was really very friendly. I felt like my friend is sitting beside me and teaching me. The way you connected the concepts of promises and async-await with the same example made me to relate and at the same time made me feel the concepts was really amazing and understanding. I know for making these videos at the backend you need to work a lot and at every moments you made me feel that you have really work a lot for making each n every concepts understand very easily. soo hats of to your hard work and dedication for making this amazing content

    For people who want just a short answer: Always use async await and not promises with .then, .catch or callbacks. But of course you need to understand promises because async await is just a sugar around them.
    P.S. don't forget to always wrap async await code in try catch block to avoid "Unhandled promise rejection".
