# --description--
|
|
|
|
The inequality operator (`!=`) is the opposite of the equality operator. Inequality means not equal. The inequality operator returns `false` when the equality operator would return `true` and *vice versa*. Like the equality operator, the inequality operator will convert data types of values while comparing.
|
|
|
|
**Examples**
|
|
|
|
```js
|
|
1 != 2 // true
|
|
1 != "1" // false
|
|
1 != '1' // false
|
|
1 != true // false
|
|
0 != false // false
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Add the inequality operator `!=` in the `if` statement so that the function will return the string `Not Equal` when `val` is not equivalent to `99`.
|
|
|
|
# --hints--
|
|
|
|
`testNotEqual(99)` should return the string `Equal`
|
|
|
|
```js
|
|
assert(testNotEqual(99) === 'Equal');
|
|
```
|
|
|
|
`testNotEqual("99")` should return the string `Equal`
|
|
|
|
```js
|
|
assert(testNotEqual('99') === 'Equal');
|
|
```
|
|
|
|
`testNotEqual(12)` should return the string `Not Equal`
|
|
|
|
```js
|
|
assert(testNotEqual(12) === 'Not Equal');
|
|
```
|
|
|
|
`testNotEqual("12")` should return the string `Not Equal`
|
|
|
|
```js
|
|
assert(testNotEqual('12') === 'Not Equal');
|
|
```
|
|
|
|
`testNotEqual("bob")` should return the string `Not Equal`
|
|
|
|
```js
|
|
assert(testNotEqual('bob') === 'Not Equal');
|
|
```
|
|
|
|
You should use the `!=` operator
|
|
|
|
```js
|
|
assert(__helpers.removeJSComments(code).match(/(?!!==)!=/));
|
|
```

```js

// Setup
|
|
function testNotEqual(val) {
|
|
if (val) { // Change this line
|
|
return "Not Equal";
|
|
}
|
|
return "Equal";
|
|
}
|
|
|
|
testNotEqual(10);
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
function testNotEqual(val) {
|
|
if (val != 99) {
|
|
return "Not Equal";
|
|
}
|
|
return "Equal";
|
|
}
|
|
```
