When/ how?
Yes. Teaching parents how to teach their toddlers to self rescue if they fall into water.
That's awesome!
Yes. for some years I helped people learn HTML and Javascript on an online forum.
Alas, Most of what I know in that area is obsolete now ;-))
Perhaps, but I bet what you taught them was a great building block for them to start picking up more. That's a beautiful thing about forums- you never know whose life you have touched.
No. Everyone else thinks they have a better way.
All of it. Now if you don't know React js you are a failure.
Then next week it will be something else.
Human computers making other human computers outdated.
Congratulations.
Most likely not. Everything is outdated.
Very rarely, if ever.
What does "js" mean?
Yes to your question (many times) and vice versa..
