## Comparison with the Strict Inequality Operator
|
||
|
|
|
||
|
|
|
||
|
|
### Problem explanation:
|
||
|
|
· _Add the `strict inequality operator` to the `if` statement so the function will return "Not Equal" when `val` is not strictly equal to `17`._
|
||
|
|
|
||
|
|
#### Hint 1
|
||
|
|
The strict inequality operator (`!==`) will return `true` if the first value is not equal to the second one taking value type into consideration.

|
**Solution ahead!**
|
||
|
|
|
||
|
|
## Basic code solution:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
function testStrictNotEqual(val) {
|
||
|
|
if (val !== 17) {
|
||
|
|
return "Not equal";
|
||
|
|
}
|
||
|
|
return "Equal";
|
||
|
|
}
|
||
|
|
|
||
|
|
// Change this value to test
|
||
|
|
testStrictNotEqual(10);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Code explanation
|
||
|
|
The function first evaluates `if` the condition `(val !== 17)` evaluates to `true` considering both value and value type. If it does, it returns the statement between the curly braces ("Not equal"). If it doesn't, it returns the next `return` statement outside them ("Equal").
