Following is the exact differences between them:

  1. The jQuery attr() method is used to retrieve the HTML attribute values while jQuery prop() method is used to retrieve the property values.
  2. The attr() method changes the attribute of the HTML tag while the prop() method changes a property for the HTML tag as per the DOM tree.
