Q
How can you invoke the print functionality in JavaScript?

Answer & Solution

Answer: Option Option C
Solution:
You can invoke the print functionality in JavaScript by using the window.print() method. This method triggers the print dialog in the browser, allowing users to choose printing options and initiate the printing process. It is specifically designed for printing web pages or specified elements within a page. The window.alert(), window.open(), and window.confirm() methods are used for displaying alert messages, opening new browser windows, and confirming actions, respectively, but they do not invoke the print functionality in JavaScript.
