How can Reactjs utilize the MutationObserver to detect changes in elements?
The provided code demonstrates the usage of the MutationObserver in a React application. This observer monitors changes to an SVG element's attributes and updates the displayed SVG code accordingly. The React component, called App, uses state to manage the SVG's size and HTML code. When the SVG size slider is adjusted, the MutationObserver detects changes and updates the displayed SVG code, allowing real-time interaction with the SVG element. The observer watches for attribute changes within the specified SVG element. The component renders an interface with a slider to adjust SVG size and displays the SVG code in a code editor.
