Read MoreDifference between 'include' and 'extend' in Ruby
In Ruby, when we are using the include keyword, we are importing a module code, but we aren't allowed to access the methods of the imported modules with the class directly because it basically gets imported as a subclass for the superclass.On the other hand, when we are using the extend keyword in Ruby, we are importing the module code but the methods are imported as class methods. If we try to access the methods that we imported with the instance of the class, the compiler will throw an error.Now let's use these two keywords in a Ruby code to ...
Read MoreHow to use the "not" keyword in Ruby?
In Ruby, we use the not keyword when we want to get an expression and then invert its Boolean value. In simple words, if an expression evaluates to True, then by using the not keyword, we will get False as the result of the expression.It can be said that the not keyword works like the "!" operator in Ruby, but the only difference between them is that the "!" operator has the highest precedence of all operators and the "not" operator has the lowest.SyntaxHere is the syntax of the not keyword in Rubynot expressionNow, let's take a couple of examples ...
