What is the tether.min.js library in bootstrap?

Question

JavaScript

For what purposes, is it possible to refuse it?

Answer 1

This is a positioning library. The Bootstrap team has used it before for positioning dropdowns, tooltips, and popovers. Now instead of this library, its more advanced counterpart is used - popper.js . If you refuse it, the components listed above will stop working. In recent versions of Bootstrap, popper.js is included by default in the bootstrap.bundle.js file. On the other hand, if you do not use tooltips and pop-ups in the project, then you can do without popper.js at all, since the drop-down menu in the navigation bar (navbar) can work without this plugin.
