Does Code Really Expire?

This question came to mind when I went back to a code I wrote a sometimes ago which worked perfectly fine and I tried to run it recently, alas! there was an error for some reasons I didn’t know of.

Then I asked myself that “has this code expired?”. In a real sense, it’s a no, but what causes a code to work sometimes ago and stop working now.

Based on my research, I found out that It was not that it expired, it was just outdated/obsolete/deprecated.

Here are some of the reasons some codes will work one time and months later, it won’t work again.

Updated Browser

Your code might not work on the same browser that it worked sometimes back because the browser has probably evolved past the code or some of the properties or versions used in your code. In this case, you have to do some research to solve the problem by installing versions that are acceptable to your browser.

Malfunction Of Third Party Code

Web apps use a variety of 3rd party codes and we use them as developers to save the time of trying to code some things from scratch but using the code developed and used by others. The problem however is that some 3rd party codes may or maybe not be kept updated with current web environments. Below are examples of 3rd party codes;

  1. Plug-ins
  2. Packages
  3. Addons
  4. Extensions…etc

In this case, 3rd party codes needs to be identified and managed to ensure it is updated and compatible with the latest standards as some packages the last update might be 5 years ago, so when looking for packages to install and download, always look out for how recent they are in making their updates.

Code Breakage

This could happen maybe someone tries to touch your code and make some changes to your code unknowing to you and the person that some part of the code has been broken. Writing tests for your code can help you notice this very quickly and try to make some adjustments.

To get started with testing, you can read my article on getting started with testing here.

These are just some of the reasons I found out that could cause your code to stop working. You can also give your point on why a code will stop working in the comment session.

I hope you find this article helpful. You can also follow me on Twitter for more tips on front-end development.
