# Precedence Of Logical Operators
|
|
|
|
There are two sets of logical operators that you are going to see in Ruby. The
|
|
more common and idiomatic set are `!`, `&&`, and `||`. Relative to all the
|
|
other operators in the Ruby language, these three have high precedence.
|
|
|
|
The other set of logical operators are `not`, `and`, and `or`. These ones have
|
|
relatively much lower precedence. Though they work conceptually the same.
|
|
|
|
The reason to be aware of the differences in precedence is that if you were to
|
|
mix the two sets, you could end up with unexpected results.
|
|
|
|
```ruby
|
|
> not true && false
|
|
=> true
|
|
> !true && false
|
|
=> false
|
|
```
|
|
|
|
To keep my Ruby code idiomatic and to avoid these kinds of potential logical
|
|
mixups, I stick to using nearly exclusively the first set—`!`, `&&`, and `||`.
