Just got the link shared from a colleague of mine and I think it is worth to read it, especially for people not dealing with JavaScript on a day to day basis:

I find that especially the concept of prototyping instead of inheritance is an important one. It does not seem to be too visible during the typical tasks, still I find it critical to understand what's actually going on under the hood of all the fanciness which the frameworks and libraries offer as abstractions.
