Anatomy of a Virtual DOM

See the visual representation of DOM nodes updating as a structured JSON blueprint.

Writing imperative DOM code requires you to manually track and update every element. It is highly prone to errors and results in logic separated from structure.

let name = "Durgesh"; let jsDiv = document.createElement("div"); jsDiv.textContent = `Hello, ${name}!`; document.body.appendChild(jsDiv);

Notice how hidden the structure is? You cannot immediately tell what the final HTML will look like just by scanning the variables because the visual hierarchy has been destroyed by imperative step-by-step logic.
