24-May-2023In JavaScript, you can store and retrieve data in the client-side cache using different mechanisms. Here are a few commonly used approaches:
1. Local Storage: The Local Storage API allows you to store key-value pairs in the client's browser. You can use the `localStorage` object to store data, which will persist even after the browser is closed. Here's an example of how to store and retrieve data using Local Storage:
2. Session Storage: Similar to Local Storage, the Session Storage API lets you store data on the client's browser. However, the data is only accessible within the current session and is cleared when the session ends or the browser is closed. The usage is similar to Local Storage:
3. Cookies: Cookies are small pieces of data stored on the client's browser. While primarily used for maintaining session information, cookies can also be utilized to store small amounts of data. JavaScript provides a document.cookie property to set and retrieve cookies. Here's an example:
4. IndexedDB: IndexedDB is a more advanced client-side database that provides a structured way to store larger amounts of data. It offers an asynchronous API for storing and retrieving objects. Here's a basic example:
These are just a few examples of how you can store and retrieve data in the client-side cache using JavaScript. The choice of mechanism depends on your specific use case, the amount of data you need to store, and the desired lifespan of the stored data.
