# --description--

The <dfn>conditional operator</dfn>, also called the <dfn>ternary operator</dfn>, can be used as a one line if-else expression.

The syntax is `a ? b : c`, where `a` is the condition, `b` is the code to run when the condition returns `true`, and `c` is the code to run when the condition returns `false`.

The following function uses an `if/else` statement to check a condition:

```js
function findGreater(a, b) {
  if(a > b) {
    return "a is greater";
  }
  else {
    return "b is greater";
  }
}
```

This can be re-written using the conditional operator:

```js
function findGreater(a, b) {
  return a > b ? "a is greater" : "b is greater";
}
```

# --instructions--

Use the conditional operator in the `checkEqual` function to check if two numbers are equal or not. The function should return either the string `Equal` or the string `Not Equal`.

# --hints--

`checkEqual` should use the conditional operator

```js
assert(/.+?\s*?\?\s*?.+?\s*?:\s*?.+?/.test(code));
```

`checkEqual(1, 2)` should return the string `Not Equal`

```js
assert(checkEqual(1, 2) === 'Not Equal');
```

`checkEqual(1, 1)` should return the string `Equal`

```js
assert(checkEqual(1, 1) === 'Equal');
```

`checkEqual(1, -1)` should return the string `Not Equal`

```js
assert(checkEqual(1, -1) === 'Not Equal');
```

# --seed--

## --seed-contents--

```js
function checkEqual(a, b) {

}

checkEqual(1, 2);
```

# --solutions--

```js
function checkEqual(a, b) {
  return a === b ? "Equal" : "Not Equal";
}
```
