🕓 History Object

Last Updated: 26th October 2025

The History Object allows you to access and control the browser's session history (the list of pages visited in the current tab).
It is part of the BOM (Browser Object Model) and helps you navigate backward or forward between visited pages.

Hinglish Tip 🗣: history object browser ke “Back” aur “Forward” button ka JavaScript version hai!

Common Properties

length	Returns the number of URLs in the session history	`history.length`

Common Methods

go(n)	Loads a specific page from the session history. Use negative numbers for backward and positive for forward.	`history.go(-1)` → Go one step back
pushState()	Adds a new entry to the session history without reloading the page	`history.pushState(, "", "/new-page")`
