Perfect candidate for a nice, simple, self-contained web component / custom element. Instead of: <div id="json-tree"></div> ... const container = document.getElementById('json-tree'); container.innerHTML = generateJSONTree(jsonData); You'd have this: <json-tree id="json-tree"></json-tree> ... const container = document.getElementById('json-tree'); container.jsonTree = jsonData; Attributes not necessary, simply pass the json data as a prop. Granted, the difference isn't that big, but this is where web components shine.
