Get jQuery version from inspecting the jQuery object
Straight to the chase, here's how you fetch the jQuery version:
And if $ isn't designated for jQuery (we're looking at you Prototype.js and MooTools), here's the zero-conflict mode:
Voila! You’ve cracked the version number and it's served as a string for your convenience.
Compatibility & troubleshooting
The version matters
Version numbers are like fingerprints – no two JavaScript libraries have the same one. Figuring out the version helps dodge any potential compatibility mishaps across different platforms.
Debugging your jQuery faults
Having the version at hand saves half the battle during troubleshooting. You could trace your steps back to any deprecated methods or pesky behavioral shifts across versions.
The $ dilemma
What’s in a name? That which we call a $ by any other name would script as well. But when library clashes occur and $ is taken, jQuery() is our sanctuary.
Scrutinizing dynamically injected jQuery
jQuery ain’t a diva! You'd still get its version number even if it dynamically enters the webpage rather than flaunting itself in the script tag.

Understanding the jQuery object
The jQuery object carries a lot under the hood. Fancy a look? Logging it will give you lots of insights:
For those who love variety
For a pinch of difference or just a natural instinct, the $()['jquery'] syntax does the trick too!
Mastering the console
The browser console is like a Swiss Army knife for developers. Mastering it could redefine your debugging game.
Working with multiple jQuery versions
Handling jQuery versions is like being at a high school reunion! All of them being present together - the drama comes free! But thanks to noConflict(), even the most quarrelsome pieces of jQuery code find peaceful coexistence.
Tools can be tricky
When spelunking in the console, ensure you are examining the right jQuery instance. Getting the two confused is like mixing up sugar and salt - yields unexpected results!
Picture Perfect
Sometimes, a well-placed image speaks louder than jargon. Screenshots of the console revealing the jQuery version could be a savior for those who find solace in visual learning.
