If we use comparison operators like <, >, <=, >= etc., "null" and "undefined" are converted to number and in such cases "null" will become 0 and "undefined" will be NaN. Lets check some of those examples. If we use comparison operators like <, >, <=, >= etc., "null" and "undefined" are converted to number and in such cases "null" will become 0 and "undefined" will be NaN. Lets check some of those examples.
#### Example - compare null with 0(zero) #### Example - compare null with 0 (zero)
```javascript ```javascript
console.log( null > 0 ); // O/P - false console.log( null > 0 ); // O/P - false

In comparison, "null/undefined" is first converted to number so, in first two cases "null" become 0 and hence case1) (null > 0) -> false and case2) (null >= 0) -> true. In comparison, "null/undefined" is first converted to number so, in first two cases "null" become 0 and hence case1) (null > 0) -> false and case2) (null >= 0) -> true.
But, in equality check (==), "null/undefined" works without any conversion and as explained above (special rule), in equality check "null/undefined" are only equal to each other and are not equal to anything else. Hence (null == 0) -> false.
