Hi Andras! Thank you for taking the time to write this. I initially planned to talk about this, hoisting and function expressions, execution context, etc. but realized that:
this blog post is a beginning of a series called "js warm-ups" and is meant as supplement to helping people understand basic js concepts in a simple way;
the blog post was getting long and therefore, potentially overwhelming for people trying to just understand what the hell arrow functions are.
I decided to split it into two (or more), this one addressing the direct need of some of my students (expressed yesterday) and the other will be published when I have time to finish it later this week. Sadly, I entitled the blog before I finished it. Just bear with me :)
I did edit the post to include the two main gotchas, though.
A developer with M.Sc. in Computer Science. Working professionally since 2010. In my free time I make music and cook.
Also I don't and after the recent events will not have Twitter.
Location

Education
Eötvös Loránd University (ELTE - Budapest Hungary) Computer Science M. Sc.
You are right, for beginners it must be scary. That's I think an inherent problem with the learning curve of JS: first it's very flat, then there's a huge uphill mountain to grasp all the quirks and gotchas (around function pointers, this and objects, immutability of Promises) and then it's very flat again.
For further actions, you may consider blocking this person and/or reporting abuse
