Bootstrap 5 data-bs-toggle vs data-toggle. Adding the bs breaks my whole Popper-CodePudding

I'm one month into learning Web Development. From what I've read, the data-bs-toggle is the newer name for Bootstrap 5.
What is the difference between Bootstrap data-toggle vs data-bs-toggle attributes?

My code is simple. In the head, I've included CSS, jQuery, and JavaScript Bundle with Popper. In the body, I have two links with a popover. In the script, I initiate popover.

By changing data-toggle to data-bs-toggle my popover wouldn't work.

data-bs-content on the other hand would not work if I change it to data-content
Why does this happen?

CodePudding user response：

You need to decide which data-toggle to initiate.

If You use $('[data-toggle="popover"]').popover() it initiates popover which has specified data-toggle

If You use $('[data-bs-toggle="popover"]').popover() it initiates popover which has specified data-bs-toggle

Stick to one version - data-toggle or data-bs-toggle

I recommend using data-bs-toggle. If You will copy code from docs, remember that DOC's describes Bootstrap 4. So if You're using Bootstrap 5 some utilities won't work with data-toggle.
