How to generate a new HTML element each time a JS function is called
Question
I have been working on a webapp that uses steam to log-in through passport and sessions. Lately I have been struggling with finding a good method to create persistent html on the page. Let me explain, here's my index.ejs:
<!DOCTYPE html>
<html lang="en">
<%- include('partials/navbar') %>
<body>
<section id="chat"></section>
<section id="main" style="flexcol center" class="flexcol">
<button id="newMatch">Create new match</button>
<div class="match"></div>
</section>
</body>
<script src=".././scripts/jquery.js"></script>
<script src=".././scripts/script.js"></script>
</html>
I have tried to make a js function that inserts a new <div class="match"></div> every time it's called but wasn't successful. Here's the code:
//CONTENT GENERATOR
let main = document.querySelector('#main');
let matchDiv = document.createElement('div');
let matchDivText = document.createElement('h3');
function createMatch(){
$(matchDivText).append('New match').appendTo($(matchDiv));
$(matchDiv).addClass('match flex center').appendTo(main);
};
$('button').click(() => {
createMatch();
});
For now, my function is not really working perfectly, It does create a new DIV, append the h2 and add the class but if called multiple times it looks like this(called 3 times):
My question is: How can i make the function create a new DIV each time and also how can I make these DIVS not go away after refresh?

The problem is that the variables are not in the function, do this:
function createMatch () {
let main = document.querySelector('#main');
let matchDiv = document.createElement('div');
let matchDivText = document.createElement('h3');
$(matchDivText).append('New match').appendTo($(matchDiv));
$(matchDiv).addClass('match flex center').appendTo(main);
};
$('button').click(() => {
createMatch();
});
