No? As an Asian student I have seen countless people try to push their children to exercise arithmetic skills because they believe that does good to their brains. However, it only misleads children to hate "math" and sometimes even their lives based on this the most important subject again and again. Moreover, children would wholly waste their exercised brain on the ruined confidence because some of them just cannot "recite" the patterns well among questions in tests, because you're required to answer too much questions during too short time, which means if you cannot recite the solution patterns from textbook and calculate the answers right at first time, you barely have no chance to try it again. Even those who did excellently in those high-school tests will face another crash at the beginning of university, because the "real math" no matter cares your arithmetic skills, but your abstract thinking and the feeling to grab and deduct rules from axiom. After all, except those real geniuses can conquer these two very different requirements and continuously get payback from that, I don't see any benefits from focusing on arithmetic with so high-strength training.
The root of all evils, as you commented: "People don’t want to learn JavaScript".
However, I think it's because DOM/BOM API sucks. JavaScript, namely the language itself, doesn't even specify any event driven or asynchronous things. Not to mention why NodeList horribly isn't an array, or the need to write the long and annoying 'getElementsByClassName' rather than a simple $( ).
(Yes I know things like 'querySelectorAll' are much better, but it's too late for most of prejudices)
someone at Google or Mozilla should already have been writing an API that's similar to jQuery that just "compiles down" to the DOM methods so that the loading of jquery isn't necessary. I'm surprised no one's pushed for using jQuery's API as an additional DOM API. Old browsers you load jquery, new browsers you don't and your code doesn't change. It would cut down on a few seconds of load time for sure and it'd be better than using a CDN.
