What is a best practice regarding subroutines in Qlik scripting?

Creating subroutines early in the script is a best practice because it enhances the readability and maintainability of the script. By defining subroutines at the beginning, developers can easily see the available functions and understand how they can be reused throughout the script. This organization allows for a more structured approach, ensuring that the logic is centralized and avoids redundancy.

Additionally, when subroutines are declared at the start, it prevents potential issues that might arise from referencing them before they are defined. This way, any part of the script can utilize the subroutine without confusion about its definition or flow. Properly structuring subroutines at the top can also help new developers quickly grasp the logic of the script, facilitating teamwork and collaboration.

Other choices can lead to complications. Defining subroutines at the end could make them harder to find and utilize. Using as many subroutines as possible without structuring can result in a chaotic codebase that is difficult to troubleshoot or enhance. Lastly, only invoking them once restricts the benefits of reusability, which is one of the main goals of using subroutines in the first place.
