• undefined When a variable is declared but not initialized, or when a function does not return a value, the variable or the function’s result is undefined. Accessing an object property or array element that does not exist also results in undefined. It is a primitive value.

• null It is a deliberate assignment that represents the absence of any object value. It is often used to explicitly indicate that a variable or object property should have no value or no reference to any object. It is also a primitive value.
