Should You be Using jQuery 3.4?
July 04, 2019
It’s Not BloatedThere are quite a few myths built up around jQuery, not least that it is bloated and slow. There’s some sense to this, containing as it does code that you probably won’t need. However this is true of all libraries, frameworks, and 3rd party scripts; unless you’re using something so niche that there is nothing superfluous wrapped up in the code, then there will always be a few bytes here and there that aren’t required.

If you’re working to a strict size quota it’s relatively simple to squeeze 71kb out of a few images. Better yet, drop a jpg and you’ll probably have room to spare.
There’s No Longer a Rich EcosystemThere was a time when jQuery developers were queuing up to deliver time-saving, feature-pushing, bolt-ons. That’s no longer the case. The web has moved on, and the gun-for-hire developers are chasing more lucrative markets, like Shopify, or WordPress. Legacy jQuery plugins (should) still work, and in the case of version 2.n plugins – thanks to the jQuery team’s commitment to backwards compatibility – will (probably) not break using 3.4. (Do make sure to test with the development version of jQuery and check your console, if you’re going down this route.) There will undoubtedly be some kind of market for jQuery 3.4 plugins, and those developers who deem it financially worthwhile to update their code will do so. So for plugins, the release of jQuery 3.4 may actually prompt a long-overdue cull.
