Difference between "and" and && in Ruby?
operators, 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".

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