In JavaScript, printing a string means displaying the contents of a string variable or literal to the console, webpage, or any other output medium. Strings are a fundamental data type in JavaScript, representing sequences of characters enclosed within single (”) or double (“”) quotes.

It is commonly used for debugging and logging messages to the browser console. You can check the printed string by going to the inspect element and then selecting the console tab.
