Question

What is the value of typeof undefined == typeof NULL?

Answer 1

The value of the expression 'typeof undefined == typeof NULL' is true.

Step-by-step explanation:

The value of typeof undefined == typeof NULL is true.

In JavaScript, the typeof operator returns a string indicating the type of a variable or expression. The undefined and null are both special values in JavaScript, representing the absence of a value or an empty value, respectively. However, their types are different.

The typeof undefined returns the string 'undefined', while the typeof null returns the string 'object'. Therefore, the expression typeof undefined == typeof null evaluates to true.
