Question

What will be the output when the following code is executed? Explain.

(false == '0')
(false === '0')

Answer 1

The first expression will evaluate to true, while the second expression will evaluate to false.

Step-by-step explanation:

The first expression (false == '0') will evaluate to true because it uses the loose equality operator (==) which only compares the values, not the types. In JavaScript, 'false' and '0' are both considered falsy values, so they are equal.

The second expression (false === '0') will evaluate to false because it uses the strict equality operator (===) which compares both the values and the types. Since 'false' and '0' have different types (boolean and string), they are not considered equal.
