Starting from jQuery 1.6, they introduced the method prop(). According to the official document of jQuery, the reason they introduced this new method is due to inconsistent behavior when using attr() before jQuery 1.6.
Before jQuery 1.6, the attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior.
Someone may ask when we have to use attr() and when to use prop(), this is how the official document said.
To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method.
That means they suggest us to use prop() when we are going to get the attributes when boolean result, like checked, disabled or selected.
