The above code snippet just change the paragraph content to "Paragraph changed". explanation: myFunction() is a function which performs this operation. It contains inbuild functions: 1) getElementById() which has a parameter demo. It checks all element in a HTML DOM(Document Object Model) (basically a tree which has all html elements in your webpage as nodes) & selects element with id "demo". 2) innerHTML is a JavaScript construct which is used to change the contents of the HTML elements. Happy Coding....😊
