I have a Shopify liquid I load into HTML Template
<script type="text/template" id="description">
<div class="product-ddd">
{{ product.description }}
</div>
</script>
<script>
$("#description").each(function() {
console.log($(this).html());
});
</script>
For some reason, find is not working
<script>
$("#description").find('h4').each(function() {
console.log($(this).html());
});
</script>
This is what {{ product.description }} returns
<div class="product-ddd">

The issue is because the <script> tag is of type="text/template". This means that the HTML within it is not rendered as part of the DOM, but instead treated as plain text.
Therefore, to get the content from it, you need to parse the string to create a DOM from it and then use jQuery (or plain JS) methods to retrieve whatever values you need from it. Try this:
let htmlTemplate = $("#description").text();
$(htmlTemplate).find('h4').each(function() {
console.log($(this).html());
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

</script>Are you sure the template parser replaces {{ product.description }} only? I suspect it replaces the whole <script></script> block. Try this way:
$(".product-ddd h4").each(function(){
console.log($(this).html());
});
