i am able to ace by frontend interviews just because of you man. Thank you so much for your efforts. This world needs more people like you. Can't thank enough. Keep up the great work! 👍🏻

[AnkitTiwari-lutt]

I had read the docs just couple of days before and now I watched your video. Understanding from docs took too much time and they didn't get fit in my mind and after watching your video the usecase of async and defer is crystal clear, that too within 8 minutes. Thanks Akshay I am totally utilising your series of Core Javascript fundamentals in this COVID-19 lockdown phase.

[srijonroy]

Man i wish you have added the "browser is the greatest thing that happened to mankind" line here too.. feels like it deserves it. Love u bro

[hellonishant]

This was the best video on async and defer attributes. Thank you Akshay

[chetanpatil]

When it comes to Javascript, You are the best.

[bhavikatibrewal]

The ways you try to make every javascript concept so easy to understand for everyone is just so great. I am short words to explain how much helpful your videos are and to thank you for all the effort.

[dev-suresh]

Thank you Akshay bhai.. Over the past year, these videos have helped a lot.

[anandsuryawanshi]

superb explanation sir ! coming from the namaste react homework

[mindblowing]

Hi Akshay, First of all, Salute your efforts 🙌 You are doing an incredible contribution toward the developer community. I'm here after completing my "NAMASTE REACT 🚀" Episode 01 - Inception and completing my assignment. You have a completely different way to teach. In this video, you have magically fed the async and defer concepts in my mind. Right now I am preparing for my React Frontend Developer Interview. Your videos helped me a lot. I also watched your "NAMASTE JAVASCRIPT" series. Such knowledge-heavy content you have generated. Thank you so much. Keep it up man😎😎😎😎

[sarwanverma]

If you explain with example then its fully understand. Thanks for this video

[RV-klwl]

Superb video. These concepts are very imp however you read about them only after the failed interview. I have been using react and web pack from 4 year and learned this concept only after failing interview.

[neyaznak]

Akshay's explanations are incredibly valuable. 8 minutes of your insightful guidance surpasses any 2-minute read. Your teaching is truly exceptional! ❤

[cybersamurai]

Thank you!!! Finally, I got this concept, appreciate it

[minigeek]

Hi Akashay, I want you to know this. I know you from your posts on linkedin. I googled frontend interview and your picture came on search. I left all other videos amd started watching. This is first video that I am watching and It was great! I never knew this concept, I can also propose this solution at my current work. You not only earned a sub, but also a fan follower. Love you! And more power to you.

[priyaranjan]

At 3:14 you came like #TheFlash ⚡
anyway thank you again Akshay!

[Jaijaishreeram]

Thanks Akshay for Crystal clear explanation.

[ganapathipranesh]

💡One more thing Akshay. "defer" will start executing the javascript code just before "DomContentLoaded" event being thrown, but "async" and "DomContentLoaded" won't wait for each other.

Nicely explained 👏🏼

[parmarav]

Hi Akshay,
Thanks for the clear explanation. If you can please explain Preload and Prefetch attributes, that would be of great help.
Topics that I can suggest are -
1. Design interview questions for Web Engineers
2. Data Structure and Algorithms to cover.
Thanks

[amardeepsingh]

Thanks bro for the amazing explanation. I was confused after reading docs on various pages...
