RailsConf 2024 - This or that? Similar methods & classes in Ruby && Rails by Andy Andrea

Using Ruby’s Delegation Methods

• Ruby’s delegation methods can lead to subtle bugs and affect garbage collection
• Methods like cover and include are similar, but cover only checks the beginning and end of the range
• Using a regular expression with capture groups can lead to unexpected behavior
• The match? method can be slow, especially when using regular expressions
• Delegating to instance variables or hardcoded strings can lead to unexpected behavior
• Monkey patching can be used to modify classes, but can also lead to unexpected behavior
• The delegate method is similar to show but uses symbols instead of strings
• Using eval or class_eval can open up classes, but can also lead to security risks
• Delegating to methods can lead to unexpected behavior and side effects
• Using send method can be fast, but RuboCop may yell at you
• Capturing groups in regular expressions can lead to unexpected behavior
• Using rescue and rescue_not_implemented_error can lead to unexpected behavior
• Using Ruby’s built-in methods like upcase and downcase can be faster
• Using include and cover methods can be similar, but cover only checks the beginning and end of the range
