Javascript library to position poppers in web applications
A popper is an element on the screen which "pops out" from the natural flow of your application.
This is version 2.x of the Popper library. The older 1.x version is available in libjs-popper.js. More recent versions have been renamed to Floating UI.
Common examples of poppers are tooltips, popovers and drop-downs.
