JavaScript Local Storage Project

'localStorage.setItem' is not a function but 'sessionStorage.setItem' is?

My function for local storage is as follows...

function localStorage(ul){

        let str = JSON.stringify(ul.outerHTML)
        localStorage.setItem("rsvp", str) 
    }

For this I get the following error localStorage.setItem is not a function whereas if I change localStorage to sessionStorage it works as expected. Using console directly localStorage works no problem. What could be the reason for this?

Your very first line is a re-definition of "localStorage" that replaces the built-in object (which does have a "setItem" method) with a new function which does not.

Give your function a different name to avoid this issue.
