Debugging Checklist

Today I just would like to list off a simple debugging checklist for you to consider when working on your own programs…

  • Ensure parentheses and curly braces match up (code organization helps this)
  • Avoid typos, especially in variable/function names
  • Be consistent with the use of single and double quote usage
  • Use escape characters (\)
  • Be careful not to use ‘=’ when you actually mean ‘==’
  • Be certain elements/objects have been created before attempting to use them (undefined error…applies to DOM elements in particular)
  • Do not create shadow variables…name global and local variables differently


The aforementioned is a simple, short list, but will go a long way in helping you avoid bugs in your code right from the start.


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.
