Array Methods & Properties


Splice allows us to remove items based upon their index position and can remove multiple items. If we run the following code with our baseball array…

baseballCards.splice(2, 1);
console.log( baseballCards );

The console will report ‘Aaron’, ‘Ruth’, ‘Uecker’ because we asked the splice operation to start at index position 2, which was ‘Wagner’ and to remove 1 item.

We can also add items to our array using splice. Any values we put after the number of items to remove will be added to the array. Consider the following…

baseballCards.splice(2, 1, ‘Cobb’, ‘Fingers’);
console.log( baseballCards );

The console will output ‘Aaron’, ‘Ruth’, ‘Uecker’, ‘Cobb’, ‘Fingers’. There are many JavaScript array methods available to us…

Happy Coding!

Unlocking Wireless Communication: A Dive into the Bluetooth API

Wireless communication has become an integral part of our daily lives, and Bluetooth technology is at the forefront of this revolution, enabling devices to exchange data over short distances and creating a world more interconnected than ever before. At the heart of this technology lies the Bluetooth Application Programming Interface (API), a powerful tool for developers looking to harness the capabilities of Bluetooth in their applications. In this blog post, we’ll explore what the Bluetooth API is, how it works, and the possibilities it opens up for innovation in wireless communication.

Understanding the Beacon API: Simplifying Asynchronous Data Transfers

In today’s data-driven world, web applications often need to send data back to the server. Traditionally, this has been done using AJAX requests or similar methods. However, these techniques can come with a cost, especially when dealing with data that needs to be sent during the unload phase of a document, such as tracking and diagnostic data. This is where the Beacon API shines by allowing developers to send data to a server more reliably and efficiently.
