Being used to jQuery, I really see no reason not to use it in new projects. I could learn all the new native equivalents, and even then still ending up doing more work than if I'd been using jQuery, just to save a little bit of page load time and filesize, but it would almost certainly not be worth it.

Indeed. I occasionally write a webbased tool to deal with a specific task (say formatting some form of codec data, or a simple dashboard for a specific event, or a small config generator, or whatever), userbase is in the <10 users (not concurrent) range, I don't give a stuff about scaling. I care that the code is in a repo (git, svn, whatever), is versioned (deb, rpm, whatever), and deploys cleanly.

I could learn and use $latest_thing, and maybe it would be great. That will triple the time taken to develop, but whatever. However in a couple of years time when I come to need to write something else, $latest_thing will be old hat, and replaced by $shiny_and_new. Rather than having 10 years of nice simple code based on jquery, I get some based on Angular, some on React, some on Vue, some on Meteor, or whatever.

I'm not a programmer, I'm not a wireman, and I'm not a carpenter. I program in the same way I'll run a network cable or get a screwdriver out, it's a tool I can use to solve a specific task. I like tools that are the same, year in, year out.

That's not to say the latest frameworks aren't all great, if you're building something for a million users and want to take advantage of shiny new features that's great, but for those that aren't, there's still a place for boring old things in a large part of the computer industry.

Take a look at zepto (or another jquery-like library), add some feature detection for IE polyfills, and switch to using fetch for ajax calls. Unless you're using a lot of jQuery dependencies, you'll cut your download size by more than half for most browsers/users.

I'd never say don't use jQuery, and it does support some options for a minimal footprint, still there's smaller options that probably have all you need.

It irks me that Javascript didn't just adopt the best parts of JQuery.

[vinceguidry]

There are still things you can only do with jQuery, I can't think of a better Swiss Army knife for small tasks.

For example, fetch() is built into browsers now but it doesn't have all the features of $.ajax()

[mxschumacher]

it irks me to use common functions such as selectors and Ajax in jQuery that are much, much slower than their native counterparts
