## Practice comparing different values


### Problem explanation:
· _Modify the function so that it returns "Equal" only when the values are **strictly** equal._

#### Hint 1
Remember from last exercises that _unlike the equality operator, which attempts to convert both values being compared to a common type, the strict equality operator does not perform a type conversion._<sup><a href="#cite1">1</a></sup>

## Spoiler alert!

**Solution ahead!**

## Basic code solution:

```javascript
// Setup
function compareEquality(a, b) {
	if (a === b) { // Change this line
		return  "Equal";
	}
	return  "Not Equal";
}

// Change this value to test
compareEquality(10, "10");
```

### Code explanation
The function first evaluates `if` the condition `(a === b)` evaluates to `true` considering both type and value. If it does, it returns the statement between the curly braces ("Equal"). If it doesn't, it returns the next `return` statement outside them ("Not equal").
