WordPress still uses
jQuery 1.x for fear of wrong compatibility with plugins and themes. They are trying to update it, but you can see that it will take a while yet (sources: one, two, three)
Now I am building a WP template where I have to use latest Bootstrap CSS framework. The problem is that Bootstrap uses the latest
jQuery 3.5.1 !
So, will the latest Bootstrap work properly with the default WordPress jQuery?
Note: I understand that I can register the latest jQuery and unregister the old ones, but this is not recommended as other plugins may use the default WP jQuery
