What is the equivalent of history.back() in terms of history.go()?

// Using history.go() to navigate
document.getElementById('goBack2').addEventListener('click', function() {
  history.go(-2); // Go back 2 pages
});

document.getElementById('goForward').addEventListener('click', function() {
  history.go(1); // Go forward 1 page
});

// Using direct methods
document.getElementById('back').addEventListener('click', function() {
  history.back();
});

document.getElementById('forward').addEventListener('click', function() {
  history.forward();
});

history.go(0)
history.go(1)
history.go(-1)
history.back() is equivalent to history.go(-1): 1) The history.go() method takes a relative position in the session history as its parameter, 2) Negative values move backward in history, positive values move forward, 3) history.go(-1) navigates to the previous page in history, exactly like history.back(), 4) history.go(-2) would go back two pages, 5) history.go(1) moves forward one page, equivalent to history.forward(), 6) history.go(0) reloads the current page, 7) These methods trigger the popstate event when used (unless there's no history entry to navigate to), 8) Understanding these equivalencies helps when implementing more complex navigation patterns that need to move multiple steps in history.
