### What it does

Disallow ternary operators.

### Why is this bad?

The ternary operator is used to conditionally assign a value to a
variable. Some believe that the use of ternary operators leads to
unclear code.

### Examples

Examples of **incorrect** code for this rule:

```javascript
var foo = isBar ? baz : qux;
```

```javascript
function quux() {
  return foo ? bar() : baz();
}
```

Examples of **correct** code for this rule:

```javascript
let foo;

if (isBar) {
  foo = baz;
} else {
  foo = qux;
}
```

```javascript
function quux() {
  if (foo) {
    return bar();
  } else {
    return baz();
  }
}
```
