Is there any wisdom behind “and”, “or” operators in Ruby?

Question

I wonder why ruby give and, or less precedence than &&, || , and assign operator? Is there any reason?

Answer 1

The difference is precedence. ||, && have higher precedence than =, but and, or have lower. So while you can do:

a = nil || 0

You would have to do:

a = (nil or 0)

to get same effect. If you do:

a = nil or 0

The result of expression would still be 0, but a value would be nil.
