Hi Yi Zhang,

I passed by changing textContent to value, i.e.

let linkName = document.querySelector("input").value;

value is a property of the element, which is being stored in the variable.

Thank you so much! I was a little bit confused about the difference between value and text content.

:point_right: You may have two issues:

  • The challenge asks you to store the value in linkName, not inputText.
  • The property of an input which holds the value entered is value.

The first problem appears fixed in the quoted code.
