Difference between "and" and && in Ruby?

What is the difference between the && and and operators in Ruby?

Solution

  • and is the same as && but with lower precedence. They both use short-circuit evaluation.

    WARNING: and even has lower precedence than = so you'll usually want to avoid and. An example when and should be used can be found in the Rails Guide under "Avoiding Double Render Errors".
