Notes
The number of triggers that you should create for a single object depends on your specific use case and requirements. However, in general, it's best to have a single trigger per object in order to keep your code organized and maintainable.
Having multiple triggers for the same object can lead to unexpected behavior, especially if the triggers have overlapping functionality or if they interfere with each other in some way. For example, if two triggers both update the same field on an object, the order in which they are executed can determine which trigger's changes persist.
Additionally, having a single trigger makes it easier to understand and maintain the code, as all of the logic related to a specific object is contained in a single place. This can be especially helpful in large projects with many developers, as it ensures that everyone has a clear understanding of what's happening with the data.
