The then keyword is not necessary in multi-line if/unless/when/in statements in Ruby. When used in multi-line statements, it can make the code harder to read and understand. This is because then is typically associated with single-line conditional statements in Ruby, and its use in multi-line statements can be confusing.
Maintaining readability and clarity in your code is crucial for effective collaboration and debugging. It becomes even more important in larger codebases, where complex logic can become difficult to follow if not written clearly.
To avoid this issue, omit the then keyword in your multi-line if/unless/when/in statements. For single-line if/unless/when/in statements, using then is acceptable and can help improve readability. This practice keeps your code clean and easy to understand, following the principles of good coding practices.
