This advice is so strange. Do you imply, that learning pure JS is not useful? I dread this attitude. Also, you cannot have "in depth" knowledge of any higher end abstraction whithout knowing the language. By definition it will always be just a superficial knowledge.

Pure JS obviously has its uses but I am assuming every professional values productivity which one can't often obtain just by knowing JS itself. JS sometimes feels like assembly, you just don't want to touch it, that's why things like TypeScript exist, for example.

Also, saying an abstraction is useless without knowing the language is similar to saying you can't drive a car without knowing how the timing belt or crankshaft works - most people do fine without either. I'm not dismissing the value of JS fluency, just suggesting that it might be unnecessary and a more practical approach can be taken.

> JS sometimes feels like assembly

Every time I see this statement, I wonder what the Venn diagram of people who say so and people who have ever written a line of asm looks like.

I don't even get it. You write Javascript basically 1:1 the same as Python or Ruby. And I would argue it's even nicer in various cases, from destructuring to lambdas to async/await and first-class Promises.

I wonder if the people say they avoid JS at all costs because it's "like assembly" have been doing that so effectively since 2003 that they never even tried modern JS

See what I was saying in the OP about the average JS developer :)

It's not even their fault, it's all they know from those online courses or boot camps.

I read a blog of a fresh grad describing ‘this’ keyword in JS. The conclusion he/she had by the end of the article was ‘don’t use “this” keyword unless you are JS expert’.

I always see a pattern with these things. Usually if you don’t learn the language well enough, you probably are also not spending enough time learning the frameworks well enough, and you probably are not learning the DOM/Browser well enough, and you probably have not learned CSS well enough. You will have no choice but to hide behind the frameworks.

The people that just learn React or the latest ES6 think they know good enough JS, but when I see their code I see clear patterns of poor abstractions, separation of concerns, the kind of code that makes you want to take a shower after touching it.

Been there. Those who assume or are hubristic enough to think they know enough can be dangerous.

I'm curious, do you have a link to the blog post?
