In this lesson, you will learn how to add a high score to a game in WoofJS, as shown in the example below. To add a high score, we will need to use the localStorage.getItem() and localStorage.setItem() functions to keep a record of the player’s high score in the browser’s local storage and then fetch this record when the player returns to the game. With Local Storage, you can store data locally within the user's browser. This data will be saved on the user’s device until they clear their browser cache.
