Error Types

Today, I want to write a short post describing the broad categories of error types…

Runtime Error

Error revealed only at runtime, such as an end user entering invalid information. Additionally, there could be issues with program incompatibility, memory issues, etc. Testing is extremely important for this error, especially if you program could be broken by an end user. Trust me…if it can be broken by an end user, they will find a way to do it.

Logic Error

Error cause by bad logic. Your code was supposed to do one thing, but it is actually built to do something else. Functioning as designed, but not as desired. This is when you go back to the drawing board. Ideally, you avoid these issues by performing your due diligence with planning lists, test plans (TDD), flowcharting and diagramming.

Syntax Error

Error resulting from violation of code rules, missing braces, missing plus signs, etc. The good news is that even though these errors are sometimes the proverbial needles in the haystack, they are typically the easiest to fix. Linters have really helped with this category (JSHint).


Understanding the basic error categories can help you diminish the number of errors and bugs introduced into your code.


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.
