  • The NOT operator is a binary logical operator in Ruby. It takes a value and returns the opposite of that value.
  • The NOT operator is used to negate a boolean expression. It takes one or more arguments and returns the negation of each argument. For example, if we want to check if 5 is greater than 2, we can use the following code:
  • if 5 > 2 #true
  • else #false

The NOT operator can be used for many purposes, but it’s most commonly used as an alternative to the AND operator. This is because using the AND operator requires two conditions for true and false, whereas using the NOT operator requires one condition for true and one condition for false.
