SO HAPY i found this link! amazing content explained slowly, clearly and reiterated...love it! i may actually learn Js now :)

[@andrewcuster6498]

Found it very promising that defer (and async, which I did not know about) were expanded on so well. Defer is something I did not come across till much later in my studies and I rarely see it.

[@haribalaji]

Great help this was ! Simple explanation and the visualization really helped. Thanks for the video.

[@skadara9555]

Maintain the same theme & coming to the presentation you're rocking as usual. Thanks for the Videos. that one suggestion front my end is to do complete video's on Front-end.

[@xBeyondMystery]

Thank you for these tutorials, I'm looking forward to learn more JS from these ones after watching a few of your other videos. Though this tutorial is from December 2020, regarding what you ask in 0:39 I personally like the dark theme best, I'm also a night owl and even if I just woke up dark themes are just easier on the eyes :) l love that you explain (with a useful visual representation) what happens in the background too!

[@DevDreamer]

Thank you! Sorry about the late reply on this, I get overwhelmed with love from you guys and it's not so easy to reply back quickly. As you may have seen we stuck with the dark theme lol, hope you are enjoying the content 🙂👍

[@Vemovemo1]

Hi, great video. i have a question, how can you execute some inline code on a script tag at the bottom of the page when the defer js files are loaded? how is the flow on this case and how can you execute scripts on this order? defer files in order -> bottom script. It must be inline scripts at the bottom, since they take some vital information from the cms page.
window.addEventListener('DOMContentLoaded', function() { ...
this coult be the way?

[@ahmetmutlu7469]

i must be late but dark theme is okey for me:DD

[@peguisreal]

I didn't understand in the whole process that what is async and defer

[@ca-lt1fc]

???...watch the video beginning at the 3:30 mark, your question is answered/explained...maybe will need to watch several times. also at the 6:19 mark, he tell you the differences as well how, when and why.

[@joeslifeproductions]

people that enjoy light theme just injoy light shows more. its not hard on my eyes

[@DevDreamer]

Hey Jospeh, 🙂 Yh same I don’t mind either way, unless I’m working late into the hours 😬 Thanks for watching 👍

[@ca-lt1fc]

i getting a little older and my hearing is beginning to fade so for me, HE SPEAKS TOO FAST and i have to turn on cc and replay several times to 100% understand him.

[@DevDreamer]

Hi Philip, firstly thank you so much for watching! I appreciate it 🙂 Secondly, I will try to slow down, I am in the process of adding subtitles to videos, so please bear with mate. 🙂👍

[@ca-lt1fc]
