vue this.$router.go(-1)

The Vue.js code "this.$router.go(-1)" is used to navigate to the previous page in the browser history.

When a user clicks on a link or performs any action that changes the URL, the browser adds that URL to its history. This allows the user to navigate back and forth between pages using the browser's back and forward buttons.

In Vue.js, the $router object represents the router instance, which manages the application's navigation. The go() method of the $router object is used to navigate to a specific page in the history stack.

By passing "-1" as an argument to the go() method, the application navigates to the previous page in the history stack, effectively simulating a click on the browser's back button.
