+##Logical Comparison
+ In order to avoid the if-else hassle, simple logical comparisons can be utilised.
+ 
+```js
+var topper = (marks > 85) ? "YES" : "NO";
+```
+In the above example, `?` is a logical operator. The code says that if the value of marks is greater than 85 i.e. `marks > 85` , then `topper = YES` ; otherwise `topper = NO` . Basically, if the comparison condition proves true, the first argument is accessed and if the comparison condition is false , the second argument is accessed.
