## Comparison with the Greater Than Operator ## Comparison with the Greater Than Operator (>)
`>` (Greater Than) is a logical operator that returns true case the value on the left is higher than the one on the right.
## Basic Solution ### Problem explanation:
· _Add the `greater than` operator to the indicated lines so that the return statements make sense._
#### Hint 1
The greater than operator `(>)` compares both operands using type coercion (converting data types if necessary) and returns `true` if the first one is greater than the second one.

## Spoiler alert!
**Solution ahead!**
## Basic code solution:
```javascript ```javascript
function testGreaterThan(val) { function testGreaterThan(val) {
if (val > 100) if (val > 100) { // Change this line
return "Over 100"; return "Over 100";
}
if (val > 10) if (val > 10) { // Change this line
return "Over 10"; return "Over 10";
}
return "10 or Under"; return "10 or under";
} }
// Change this value to test
testGreaterThan(10);
``` ```
### Code explanation
The function first evaluates `if` the condition `(val > 100)` evaluates to `true` converting `val` to a number if necessary. If it does, it returns the statement between the curly braces ("Over 100"). If it doesn't, it checks if the next condition is `true` (returning "Over 10"). Otherwise the function will return "10 or under".
