Considering there is easily (in US) 60-80K+/year difference between doing HTML + CSS + JS (mostly via jQuery) and say React. Spending 1 month to learn webpack + React looks like fairly sound investment of time.
There are no longer any HTML, CSS, JS jobs posting without the fact of needing to know one or multiple JS frameworks.
If you are currently working and using no frameworks in your current job you better learn them before looking for your next gig. Because if you don't you are no longer relevant .. .speaking from current job hunting experience and 30 interviews yet no offers.
One interesting question might be why the reverse isn't true: if companies could spend 60k less per head (or even 30k less per head) by hiring developers who demonstrate facility with HTML+CSS+JS+jQuery and then training them over a few weeks in webpack+React (while getting them up to speed with the particulars of their codebase, which is inevitably going to be a thing anyway), why wouldn't they do that?
Two reasons: recruiting departments head recruiting and they use keyword filtering tools to limit their nets.
The second reason is that nobody (as far as I can tell) seems to be hiring to train anymore. They just want full capacity from everyone and there’s a lot of myth out there about how an unskilled contributor can be a huge detriment.
Seeing you get downvoted, I don't get it. Why would professionals not want to spend a week to learn something which you can build knowledge on for the next few decades, especially when it has monetary value?
There's an aggressive/paradoxical luddism in tech that I'll never understand, considering that it is the tech industry. How many great tools/frameworks have come out over the past decade and how limited would you be if you ignored it all?
Few survived a decade though... I doubt that changed with the current generation.
Not saying it's not with the effort to learn. Just had to smile about your time reference
