JavaScript Button input and output reset

I’m working with a button and a text label in javascript and HTML. I have a code that clears the input text label, but i also need the same button to clear the output message it gives = “helloNameOP”. How would I add the 2 in the same function? I have both my codes listed below, that work perfectly separated, but I cant figure out how to put them together to work simultaneously.

What I have tried:

 //for removing the Input text label:
onclick = document.getElementById("helloNameInput").value="";


//for removing the Output message recieved:
inputField = document.getElementById("helloNameOP")
document.getElementById('helloNameOP').textContent = " "

I’m not a javascript person, more of a kotlin gal, so I’m trying to learn.
