element using the classList
property.
Look at the following example
to see the classList property
in the console:
The classList property returns
a list of all the class attributes
of the h1 element.
In the console for the above code
we can see the class name highlight.
We can add class names to this list
using the add method.
Let us take a look at the following
example to understand how to add classes:
As we can see see in the console,
we get two class names now.
The highlight and the complete
classes are both now present on
the h1 element.
