Appian ACD101 Exam - Topic 2 Question 19 Discussion

You are using a local variable in an expression rule to describe the height of an applicant.Which statement correctly describes the application of Appian best practices for naming your local variable?
B) local!applicantHeight - This employs the naming convention of specifically describing the value contained by the variable.
A) local!hoaa - This employs the naming convention of abbreviating 'Height of an applicant' to minimize both the typing required by developers and the length of code Appian is required to parse.
C) local!x - This employs the naming convention of using algebraic variables for a value that may either change over time or be used by future developers for other purposes.

[All ACD101 Questions]

You are using a local variable in an expression rule to describe the height of an applicant.

Which statement correctly describes the application of Appian best practices for naming your local variable?

Show Suggested Answer Hide Answer
Suggested Answer: B

The best practice for naming variables in Appian is to use clear and descriptive names that convey the purpose or content of the variable. Therefore, local!applicantHeight is the best option as it precisely describes the value contained by the variable, which is the height of an applicant. This naming convention aids in readability and maintainability of the code, making it easier for developers to understand and modify the code in the future.

I’m a bit confused about option C. Using 'local!x' seems too vague, but I guess it could work in some contexts? I’m not sure if it’s best practice though.

I'm not entirely sure, but I feel like using abbreviations like in option A could lead to confusion later on. We should aim for descriptive names, right?

I think the best approach here is to use the most descriptive variable name possible, which would be option B. "local!applicantHeight" clearly communicates the purpose of the variable, which is important for maintainability and understanding the code.

Option A seems like it might be the right answer - "local!hoaa" to abbreviate "Height of an Applicant". That would follow the convention of minimizing typing and code length. But I'm not 100% sure.

Appian devs who use 'local!x' must also prefer their variable names to be as mysterious as their codebase. Just sayin'.
