Ruby typeof - Ruby

Ruby typeof is a method in Ruby that allows you to determine the type of a given object or variable. The typeof method can accept one argument which is the object or variable you want to determine the type of.

Syntax

The syntax for the typeof method is as follows:

typeof(object)

Where object is the object or variable you want to determine the type of.

Examples

Here are some examples of using the typeof method:

typeof("hello world")  # String
typeof(42)             # Integer
typeof(3.14)           # Float
typeof(true)           # TrueClass
typeof(false)          # FalseClass
typeof(nil)            # NilClass
typeof([])             # Array
typeof({})             # Hash
typeof(:symbol)        # Symbol
typeof(/regex/)        # Regexp
typeof(-> { puts "hello" }) # Proc
typeof(lambda { puts "world" }) # Proc
typeof(class MyClass; end) # Class
typeof(Module.new)      # Module
typeof(Object.new)      # Object

As you can see, the typeof method returns the type of the given object or variable as a string.

Conclusion

The typeof method in Ruby is a useful tool for determining the type of a given object or variable. By knowing the type of an object or variable, you can write more effective and efficient code.
