Debugging Tips

Today’s post is a simple one…tips for debugging. I have said it before and will say it again…Everyone’s code has bugs in it. Mastering debugging techniques will give you ninja-like skills in smashing out bugs. So these are just a few tips I have incorporated into my debugging over the years…

  • Handle them one at a time. Sometimes the amount of bugs can be overwhelming. Focusing on one at a time makes the task surmountable. Additionally, sometimes fixing one bug fixes others in the same process. Over time and with practice/experience, you will learn which ones to address first in your program that will fix others.
  • Organize your code. This is critical. Messy code leads to more bugs. Think of it like your house…leaving food scattered across your counter is inviting to ants. Putting it away in containers in the fridge…no ants. Use proper indentation, comments, etc. This will allow you to see where you might be missing a curly brace or parenthesis more easily. Side note: some IDEs have ways to do this easier for you. Some do it automatically. For example, when I use Brackets, I use a plugin called Beautify that cleans up my code for me.
  • Double check your spelling. In a case sensitive language, such as JavaScript, this is even more critical. 
  • Do not forget to escape characters. Have a quote you want to output to the screen? Forget to escape it and it might become a bug.
  • Shadow variables. Be aware of the scope of your variables and when a local variable might overwrite a global variable of the same name. Better still…do not have two variables with the same name.

These are just a few tips for you. There are more, but these are the ones that in my experience have helped me out the most.

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.
