Multiline Conditional Expressions should be avoided
[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]This code insight counts one violation each time a multiline conditional expression is encountered.

Why you should care
[/vc_column_text][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]Conditional expressions are mechanisms that provide a shorter syntax for if statements. For example: x = 1 if cond else 2.
May be harder to read than an if statement. The condition may be difficult to locate if the expression is long.
Okay to use for one-liners. In other cases prefer to use a complete if statement.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text pl=”0″ pr=”0″ pt=”0″ pb=”0″]
Business Impacts
It is recommended to avoid these in order to ensure the code is more readable and cost effective.
