What is the difference between the && and and operators in Ruby?
915
There is typically a better way to say whatever is being said but it does convey a specific meaning. You should use and/or when both options are applicable in its place. "I would like cake and/or pie" means "I would like one or both of the following: cake; pie."
An is a determiner that means "the indefinite article before nouns with a vowel sound". And is a conjunction that means "expressing two elements to be taken together or in addition to each other". Let's take a closer look at each word. An is an indefinite article.
and is a Logical AND that returns True if both the operands are true whereas '&' is a bitwise operator in Python that acts on bits and performs bit by bit operation. Note: When an integer value is 0, it is considered as False otherwise True when using logically.
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".
