3,339 PointsThis challenge is about adding a class of "highlight" to a <p> element that's an immediate previous sibling of the button being clicked.
The e.target is the reference to the button element, the previousElementSibling property can locate the immediate previous sibling, and the className property can set the value of the class attribute.
