method of the

interface returns an array of NavigationHistoryEntry
objects representing all existing history entries.

entries()
Parameters
None.

An array of NavigationHistoryEntry
objects.
Exceptions
None.
Examples
Return the number of entries in the history
js
let numOfEntries = navigation.entries().length - 1;
A smart back button
A page-supplied "back" button can take you back, even after reload, by inspecting the previous history entries:
js
backButtonEl.addEventListener("click", () => {
if (
navigation.entries()[navigation.currentEntry.index - 1]?.url ===
"/product-listing"
) {
navigation.back();
} else {
// If the user arrived here in some other way
// e.g. by typing the URL directly:
navigation.navigate("/product-listing", { history: "replace" });
}
});
