This repository demonstrates a simple component that updates the DOM based on JSON changes. Only the changed parts of the page are updated; elements that stay the same are not reloaded.

• index.html – demo page that loads the component and shows an automatic update after two seconds.
• updateComponent.js – contains the JSONUpdater class that uses fast-json-patch (included as fast-json-patch.min.js) to detect changes and update the DOM accordingly.

Open index.html in a browser. The page will display a fruit list that gets partially updated after two seconds. Only the modified list items are replaced.

The component can be reused by calling component.setState(newState) with new JSON data.
