Hey Dev Dreamer, thanks for another great video! Also, I like the dark theme, and I think it works well. Keep doing what you’re doing!

[pavankalyan-ckvx]

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.

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.

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!

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?

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
