What is the JavaScript equivalent of clicking the browser's Back button?

The function history.go(-1) is indeed the JavaScript equivalent of clicking the browser's Back button. This method interacts with the browser's session history and allows for navigation to a previous page. When you pass -1 as an argument, it tells the browser to go one step backward in the history stack.

Understanding the history object is crucial in this context, as it contains the ability to manipulate the history of URLs that the user has navigated. The go() method, which is part of the history object, is quite flexible and can also take positive numbers to go forward in history, or zero to reload the current page.

This functionality is a commonly used feature in web applications where developers wish to provide a way for users to reverse their navigation, similar to how they might using the browser interface. The other options, while hinting at similar functionality, do not specifically align with the standard JavaScript API for history manipulation in the same way as history.go(-1).
