How do I get the value of a custom div variable in Javascript?

I have this div in my reactJS project:

<div
              className="td-creator"
              id="Creator"
              tooltiptext="Melder"
              onMouseOver={setToolTip}
              onMouseOut={hideToolTip}
            >

I am trying to get the value of tooltiptext by using getelementbyid.
I can succesfully store the div element in a variable name target and when I print it in the console it shows me this:

but when I try to use target.tooltiptext it returns undefined.
is there any way to acces the tooltiptext value in Javascript?

>Solution :

This is because tooltiptext is not a property of the HTMLDivElement.

Try getAttribute:

const toolTipText = target.getAttribute("tooltiptext");
