Sequencing/Order

Sequencing is the order in which elements are put together. A simple example of this can be a morning routine. It may start with getting out of bed, then brushing your teeth, then getting dressed, then eating, and finally leaving for school. These sequences of events are placed in a logical order that makes sense. This can be applied to coding. When making programs it is essential that the code works but is also important that it makes logical sense. For example, in a game chooser app, you would want to filter the apps to get a specific genre and then choose the game rather than choosing the game and then filtering the list of games. This can be applied to any type of code created as sequencing is essential. The incorrect sequencing of code may often cause the program to not work although the code itself may be correct.

I had to implement sequencing in my create performance task app as I made quite a few mistakes in my program. I needed to create a way in which I filtered my list upon a certain action like a button press. The sequence of actions when the buttons would matter as the code would loop and with this came the issue. Due to an error in sequencing my code would never end causing my app to not work upon the button press. A simple re-order of my code led me to fix my code and work correctly. Several of my peers also ran into this issue as they also had issues with the filters they used in their code. Although some were easier to fix than others, these mistakes had a major impact on the functionality of their code.
