What are the subtle differences between toggleClass and addClass and removeClass?

Question

JavaScript

It is clear that toggleClass works like a class switch, and addClass only adds a class, and removeClass removes, but what are the subtleties of using these methods? When should one be used and when should the other?

Answer 1

toggle is an abstraction over successive calls to add-remove-add-remove...
It is used only in rare cases when it is known to always change the value to the opposite.
