    Your videos are excellent - amongst the best. You move quickly, waste zero time, and get right down to brass tacks. No fluff, lame banter, etc. I wish all course authors were as sharp and succinct! Well done, I like your style.

      Agreed. and my next compliment has nothing to do with the content - I genuinely think he's good looking. Not flirting though, just stating the truth about his appearance. He looks clean, tidy and healthy. If only majority of devs could take care of their health more. And his skin is flawless and glowing! Not sure if he used any filter when recording this vid, but nevertheless, tell me your secret @ByteGrad !😅

    what I like about your videos is that I feel like you know what you're talking about. I really don't like learning bad practices and many tutorials unfortunately teach those because nobody is perfect of course :D but I really like that it's doesn't sound like you are repeating something you've read yesterday but it is what you really know and understand and it isn't "just because" but it has a reason. thank you

  • @sudarshan_savvy
    @sudarshan_savvy 7 місяців тому +10

    You are the best tutor; you know how to teach concepts very well. I have taken many paid courses and learned from more than 50+ UA-cam tutors, no one matches your teaching style. Perfect pace, not slow, not fast, just 100% perfect. Clear concepts with practical examples. Thanks.
    Your voice is relaxing but was bit low in this video.

  • @gurpritsingh3164

  • @gosnooky
    @gosnooky 8 місяців тому +1

    Nice thing about tuples, you can unionize them for different lengths. If you accept 4 numbers for padding for [top, right, bottom, left] or 2 values for just top and bottom ([x, y]), say, you could annotate tuple elements: padding: [x: number, y: number] | [left: number, right: number, bottom: number, left: number], then compute your padding based on the array length.

    I would of loved to watch this video 4 years ago when i was looking for a new job and i applied for one in which typescript was a nice-to-have requirement and when i joined the project it turned to be a whole react/node project written in TS. Everything you explain along the video i learned it struggling and pulling my hairs off of my head lol. Now i watched your video out of curiosity and i can say it's the best "Everything you need to know" video i've seen according to my experience. You really nailed it!

      Exactly 💯, it's good to see videos like this, JavaScript mastery released a video recently saying React isn't NextJs and he talked about server components and how we must change the way we think when using the new nextJs 13 app router, the new changes can be a bit overwhelming especially for newbies just transitioning from react to nextJs, I still use the old pages directly for my learning for now, I feel the app router to be confusing

    Hey, just saw your video on useEffect mistakes and I wanted to hear your explanation of the key prop importance in React. I saw many videos and read posts that talk about it but never saw a real world example with complex applications. Let's say for a product component with multiple properties to map in nested React nodes, where should we put the key prop, and what should it be?
    Thanks for your perception!

    I've learned a lot more in 1 day of watching your videos than following through a 7hr tutorial of building an app. I get overwhelmed with some of the small stuffs that they dont explain and ended up just doing a copy paste instead of actually learning, dont get me wrong, they are good and I appreciate the time and effort they give to produce such contents, its just its not beginner friendly, and you sir gave me all the basic ideas i need to understand those tuturials fully. So i wouldn't mind purchasing for your course coz i know I will learn a lot more. Hope you release it soon!
