lit-html Count Example

lit-html-count.js

import { html, render } = from 'lit-html';

// A lit-html template uses the `html` template tag:
const countTemplate = (count) => html`<p>The current count is: ${count}</p>`;
      
let i = 0;
setInterval(() => {
  // Renders with the `render()` function
  // + re-renders only update the data that changed, no VDOM diffing!
  render(countTemplate(i++), document.body)
}, 1000);
