Modifying HTML Content and Attributes

element.classList.toggle('active');
element.classList.toggle('active', true);
element.classList.toggle('active', false);

They all do the same thing
The first toggles, second forces add, third forces remove
classList.toggle() has two forms. Without a second parameter, it toggles the class (removes if present, adds if absent). With a boolean second parameter, true forces the class to be added, false forces it to be removed, regardless of its current state. This is particularly useful when you need to set a class based on a condition, making your code more concise than using if statements with add() and remove().
The second and third have no effect
The first is deprecated
