CodeParkconsole.log(null == 0, null >= 0, undefined == null, undefined == 0);
false true true false
Loose equality (==) has a special rule for null and undefined. They are equal to each other and to nothing else. So null == 0 and undefined == 0 are both false, and undefined == null is true.
Comparison operators like >= follow a different rule. They convert both sides to numbers. null becomes 0, so null >= 0 becomes 0 >= 0, which is true.
The tempting option "false false true false" is wrong because it assumes >= uses the same rule as ==. It does not.
