Popper.js, a 3KB library to manage tooltips and popovers

In plain words

Popper.js is a 3KB JavaScript library that positions floating elements like tooltips and popovers on web pages. It handles the technical work of calculating where these elements should appear relative to other page content and managing user interactions with them. The library is useful for developers building web interfaces that need dropdown menus, tooltips, or other floating UI components.
