In Ruby, it is recommended to use the instance_of? method for class comparison. This is because instance_of? only returns true if the object is an instance of that exact class, not a subclass. The method provides a strict way of checking an object’s class, which helps in maintaining the integrity of the code.
Using other methods such as something.class == Date or something.class.equal?(Date) are not considered good coding practice. These methods could lead to unwanted behavior, particularly if the object’s class is a subclass of the specified class.
To adhere to this rule, always use something.instance_of?(Date) when you need to check if an object is an instance of a specific class. This ensures the object is exactly an instance of the class, not a subclass, providing more accurate and reliable results. This practice can help avoid potential bugs and make your code more robust and easier to understand.
