Sally the Camel has…One Hump

Unwritten rules…every organization, every industry has them. Some ‘rebels’ asky why we do them. Sometimes there is a good reason and sometimes there is not. Today I would like to discuss a standard naming convention in programming, particularly when it comes to variables. This convention is entitled, ‘Camel Case’.

Here is an example of a variable utilizing camel case…

[code lang=”js”]
var myVar;

Camel case is when you capitalize the first letter of the second word in a compound word. If it were not a compound word, it should be all lowercase. Specifically, this is called lower camel case. Upper camel case is when you capitalize the first letter of every word. Lower camel case is the standard.

Now, do you have to do this to get your programming to work? In most cases, no, but it is a standard. Why? Mostly for human readability. It is a lot easier for our human eyes to read through code and see these and understand them.

So, if you are not using camel case, begin using it in your code today and make your code easier to read.

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.
