Counting to Five

In my last post, I discussed looping. I referenced checking the condition to see whether your code should keep looping or not. This is usually done with a counter (i).

for (var i = 0; i < 3; i++;) {

Look closely at the i++ piece. ‘++’ is a shortcut for incrementing. Every time the loop runs one (1) gets added to the value of ‘i’. So ‘i’ starts at zero (0), then goes to one (1), then two (2), etc. This will alter the condition and help control how often the loop runs.

FYI, you can also decrement using ‘–‘.

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.
