His teaching skill is outstanding. I learn most of programming from his tutorial.☺

<*_> This is my seal. I have watched the entire video, understood it, and I can explain it in my own words, thus I have gained knowledge. This is my seal. <_*>

this is what is different in these lessons than all the other people and posts I've come across teaching JS.

Why

this is what bugs me. they don't tell me Why I would be doing this or that. they don't show me where I could use any of these things. examples and reasons, so very important for me to understand complex concepts .

I can't just drone-like take in and memorise everything a lesson giver tells me if I don't know what I can use it for.

if i itterate the age value with age++ instead of age+=1 its type is converted into number, even if i don't have to use age=Number(age). Interesting!

Kinda funny how "Not a Number" NaN returns as a number.

Can we do this? Declaration let varName = number (1);
