Is This WorkAround to Get Submitted Form Values to Persist Poor Form?

JavaScript

Hello,

I’m working on the palindrome checker and I found a workaround to get the code in the block to persist in the browser after clicking submit.

<form onsubmit="checkForPalindrome(); return false">

If I didn’t include ;return false then the following code would vanish immediately after flashing in the broswer.

let userInput; // Even this returns to undefined after the click event!

function checkForPalindrome() {
    userInput = document.getElementById('text-input').value
    console.log(userInput.length)
    positiveResult.style.display = 'block';
}

Can someone help me understand why the values I log in the code block do not even remain in global variables?
