Good evening, I have an HTML file and I need to display on the page some variables that are in my Javascript, as I could make this connection?

Good afternoon. Maybe this can be useful:
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
</head>
<body>
<div>
<h1 class="jsH1"></h1>
<input type="text" class="jsInput">
</div>
<script>
$(document).ready(function() {
//Nós definimos variáveis
var h1Content = 'Titulo pra o H1';
var inputContent = 'Valor do input';
//Nós carregamos as variáveis anteriores para seus respectivos contêineres
$('.jsH1').text(h1Content);
$('.jsInput').val(inputContent);
})
</script>
</body>
</html>

You can use jQuery as it was published here or do this with just Javascript with innerHTML.
<div id="campo1">
a
</div>
<script>
variavel = 5;
document.getElementById("campo1").innerHTML = 'Valor da variavel: '+variavel;
</script>
innerHTML is used to pick up or set all the HTML of a particular page element, in our case it was from the div that has the id campo1
