# --description--
|
||
|
||
另一种数据类型是<dfn>布尔</dfn>（Boolean）。`布尔`值要么是`true`要么是`false`。它非常像电路开关，`true`是 “开”，`false`是 “关”。这两种状态是互斥的。
|
||
|
||
**注意**
|
||
`布尔值`是不带引号的，`"true"`和`"false"`是`字符串`而不是`布尔值`，在 JavaScript 中也没有特殊含义。
|
||
|
||
# --instructions--
|
||
|
||
修改`welcomeToBooleans`函数，让它返回`true`而不是`false`。
|
||
|
||
# --hints--
|
||
|
||
`welcomeToBooleans()`函数应该返回一个布尔值 (true/false)。
|
||
|
||
```js
|
||
assert(typeof welcomeToBooleans() === 'boolean');
|
||
```
|
||
|
||
`welcomeToBooleans()`应该返回 true。
|
||
|
||
```js
|
||
assert(welcomeToBooleans() === true);
|
||
```
|
||
|
||
# --seed--
|

|

## --after-user-code--
|
||
|
||
```js
|
||
welcomeToBooleans();
|
||
```
|
||
|
||
## --seed-contents--
|
||
|
||
```js
|
||
function welcomeToBooleans() {
|
||
|
||
// Only change code below this line
|
||
|
||
return false; // Change this line
|
||
|
||
// Only change code above this line
|
||
}
|
||
```
|

# --solutions--
|

```js
|
||
function welcomeToBooleans() {
|
||
return true; // Change this line
|
||
}

```
