## Use the Conditional (Ternary) Operator
|
||||
|
||||
### Hint 1
|
||||
Use ternary operator to check for equality.
|
||||
### Problem explanation:
|
||||
_Use the `conditional operator` in the `checkEqual` function to check if two numbers are equal or not. The function should return either true or false._
|
||||
|
||||
### Warning Solution Ahead!!!
|
||||
#### Hint 1
|
||||
Remember that the "traditional" `if...else` syntax can be re-written using the conditional operator (`condition ? statement if true : statement if false;`)

## Spoiler alert!
|
||||
|
||||
**Solution ahead!**
|
||||
|
||||
## Code solution:
|
||||
|
||||
```javascript
|
||||
function checkEqual(a, b) {
|
||||
return (a == b ? true : false );
|
||||
return a === b ? true : false;
|
||||
}
|
||||
|
||||
checkEqual(1, 2);
|
||||
```

|
||||
|
||||
### Code explanation
|
||||
- The function checks if the `condition` before the interrogation sign (`?`) is true, and if so, executes the `true` statement. Otherwise, it returns `false`.
