This code snippet is essential to ensure that your website or web application will work in all modern browsers, as not all browsers may support the Mutation Observer API. By using this code snippet, you can ensure that your code will only be executed if it is supported by the browser.
-MutationObserver is a new object introduced in HTML5 which allows you to observe changes to the DOM (Document Object Model) in a browser.
-It uses the observer pattern, which means that you set up a listener and then receive notifications when changes occur.
-It is non-blocking and asynchronous, meaning that you don’t have to wait for changes to be completed before receiving new changes.
-Mutation Events are an older way of observing DOM changes.
-The events are blocking, meaning that code execution will pause until all handlers for the event are completed, which can lead to performance issues.
-Mutation Events are less reliable than MutationObserver since they can be cancelled or postponed.
