# --description--
|
|
|
|
Strict equality (`===`) is the counterpart to the equality operator (`==`). However, 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.
|
|
|
|
If the values being compared have different types, they are considered unequal, and the strict equality operator will return false.
|
|
|
|
**Examples**
|
|
|
|
```js
|
|
3 === 3 // true
|
|
3 === '3' // false
|
|
```
|
|
|
|
In the second example, `3` is a `Number` type and `'3'` is a `String` type.
|
|
|
|
# --instructions--
|
|
|
|
Use the strict equality operator in the `if` statement so the function will return the string `Equal` when `val` is strictly equal to `7`.
|
|
|
|
# --hints--
|
|
|
|
`testStrict(10)` should return the string `Not Equal`
|
|
|
|
```js
|
|
assert(testStrict(10) === 'Not Equal');
|
|
```
|
|
|
|
`testStrict(7)` should return the string `Equal`
|
|
|
|
```js
|
|
assert(testStrict(7) === 'Equal');
|
|
```
|
|
|
|
`testStrict("7")` should return the string `Not Equal`
|
|
|
|
```js
|
|
assert(testStrict('7') === 'Not Equal');
|
|
```
|
|
|
|
You should use the `===` operator
|
|
|
|
```js
|
|
assert(__helpers.removeJSComments(code).match(/(val\s*===\s*\d+)|(\d+\s*===\s*val)/g).length > 0);
|
|
```

|
|
```js
|
|
// Setup
|
|
function testStrict(val) {
|
|
if (val) { // Change this line
|
|
return "Equal";
|
|
}
|
|
return "Not Equal";
|
|
}
|
|
|
|
testStrict(10);
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
function testStrict(val) {
|
|
if (val === 7) {
|
|
return "Equal";
|
|
}
|
|
return "Not Equal";
|
|
}
|
|
```
