How to create Material Icon with Pure JavaScript

I'm thinking about how to create Material Icon with pure JavaScript(document.createElement)

const iconBox = document.createElement("div");
iconBox.style.width = "28px";
iconBox.style.cursor = "pointer";
iconBox.style.display = "flex";
iconBox.style.opacity = "1";
iconBox.style.position = "relative";
iconBox.style.alignItems = "center";
iconBox.style.justifyContent = "center";
iconBox.style.backgroundColor = "#ffffff";

const svg = document.createElement("svg");
svg.style.width = "1em";
svg.style.height = "1em";
svg.style.flexShrink = "inlineBlock";
svg.style.transition = "fill 200ms";
svg.style.flexShrink = "0";
svg.style.userSelect = "none";
svg.style.fontSize = "2.1875rem";

const path = document.createElement("path");
path.setAttribute(
  "d",
  "M14.59 8L12 10.59 9.41 8 8 9.41 10.59 12 8 14.59 9.41 16 12 13.41 14.59 16 16 14.59 13.41 12 16 9.41 14.59 8zM12 2C6.47 2 2 6.47 2 12s4.47 10 10 10 10-4.47 10-10S17.53 2 12 2zm0 18c-4.41 0-8-3.59-8-8s3.59-8 8-8 8 3.59 8 8-3.59 8-8 8z"
);
svg.appendChild(path);
iconBox.appendChild(svg);

const container = document.getElementById("container");
container!.appendChild(iconBox);
console.log(container, "container");

But somehow, in a web browser, the icon doesn't show up(The div, svg, and path are there)

This is a screenshot of a web browser console.

enter image description here

This is my codesandbox, the whole code is there.

Because svg elements are XML rather than HTML, the elements need to be created with the appropriate namespace. So instead of

document.createElement("svg");

and

document.createElement("path");

you need to use:

document.createElementNS("http://www.w3.org/2000/svg", "svg");

and

document.createElementNS("http://www.w3.org/2000/svg", "path");

Edit Pure Typescript
