Answer / Bhavana Gautam
== is a comparison operator that checks if two objects are equal. It works for most object types but may not work correctly with custom objects or classes. === is a match operator that determines if an object matches the specified class or module. It's often used in conditional statements like `if obj == MyClass` or `if obj instanceof MyClass`. eql? is a method that returns true if two objects are equal and their types are the same. Equal? is another comparison method that checks for both equality and object identity (it only works with reference types like arrays, hashes, and classes).
