femtoJS VS umbrella

If you are mainly using jquery for its DOM manipulation¹ rather than for browser compatibility² or things that didn't exist consistently in older browsers³ then there are much smaller libraries that do that job which may be worth looking into. https://github.com/fabiospampinato/cash or https://github.com/franciscop/umbrella to give a couple of examples. Some explicitly support IE11 so you are not dropping as much support for legacy browsers as you might otherwise.

Though if jQuery works for you and isn't a performance issue, then by all means keep with it. It may not be ideal, but good enough and does the job. Let the naysayers spend their time debating whether you should or not, and just get on with making things!

[2] not the issue it once was, if you can abandon IE and old Android browsers from your supported UAs or can deal with any issues that crop up individually

[3] again, if you can afford to drop support for legacy UAs

Yes, and if you continue long enough you end up with one of the many jQuery alternatives, like mine:

If you're learning React just to get a job, you're doing it wrong, since recruiters are always changing their requirements. They will add `proficient in Svelte` just to annoy you, (after having learning React) and now you're no longer relevant to them.

That's why I say: stick to the baseline of HTML, CSS, & JS. Learn to write vanilla JS for common things, maybe learn UmbrellaJS[0] for syntactic sugar and manipulating the DOM.

Oh and learn some APIs to do back-end stuff too. And for forms, there's loads of projects out there to automate that[1]

const insertAfter = (col, html) => col.forEach(el => el.insertAdjacentElement('afterend', html));

Keep going a bit like that, until you realize you are basically reinventing jQuery. Add a couple of very nice-to-haves, like chaining (instead of nesting in these examples above) and that's exactly what Umbrella JS is, very thin methods to manipulate the DOM and handle events. In fact, compare our "addClass" implementation in this comment to [Umbrella's addClass](https://github.com/franciscop/umbrella/blob/master/src/plugi...), it's almost the same size but hundred times more flexible:

// Add class(es) to the matched nodes
