classList method in javascript | DOM methods in javascript | learn javascript #classlist #javascript

We use classList and className on JavaScript DOM to manipulate classes.
These two DOM property has different use cases. In this video, I have shown what is the difference between classList and className.
The className property returns the name of the classes in the form of a string, whereas the classList property of JavaScript returns the name of the classes in the form of an array.
add(): The add() method is used for adding one or more classes to the element.
remove(): The remove() method is used for removing one or more classes from the number of classes present in the element.
toggle(): The toggle() method is used for toggling the specified class names of an element. It means on one click the specified class gets added and on another click the class gets removed. It is known as the toggle property of an element.
replace(): The replace() method is used for replacing an existing class with a new class.
contains(): The contains() method of the JavaScript classList property is used for returning the Boolean value as an output. If the class is present, the value is returned as true otherwise false is returned.
item(): The item() method is used for displaying the name of the classes at the particular index. Thus, it returns the class name.
