In this tutorial, we will learn how to set a value in sessionStorage using JavaScript. sessionStorage is a web storage object that allows storage of key/value pairs in the browser for the duration of the session.

To set a value in sessionStorage, we can follow these steps:

1. Start by accessing the sessionStorage object using window.sessionStorage. This object has methods to interact with the storage.

2. Use the setItem() method to set the key/value pair in the storage. Pass the desired key and value as arguments into this method.

Here is an example code snippet that demonstrates how to set a value in sessionStorage:

// Set a value in sessionStorage
window.sessionStorage.setItem('key', 'value');

In the above code, we are using the setItem() method to set the value 'value' for the key 'key'.

Using sessionStorage.setItem() will store the value in the browser’s sessionStorage. This value will persist until the session ends or until it is cleared.

Note: The setItem() method overwrites the existing value if the same key is used again.

That’s it! You have now learned how to set a value in sessionStorage using JavaScript.

Conclusion

In this tutorial, we discussed how to set a value in sessionStorage using JavaScript. The sessionStorage object is a powerful tool for storing data in the browser’s session. By utilizing the setItem() method, you can easily set and update key/value pairs in sessionStorage.
