## 练习比较不同的值
|
|||
|
|
|
|||
|
|
### 问题解释：
|
|||
|
|
|
|||
|
|
· _修改函数，使其仅在值**严格**相等时返回“Equal”。_
|
|||
|
|
|
|||
|
|
#### 提示1
|
|||
|
|
|
|||
|
|
请记住，在上一次练习中， _与等于运算符不同的是，它尝试将两个值转换为常见类型，而严格相等运算符不执行类型转换。_ [1](#cite1)

|
## 基本代码解决方案
|
|||
|
|
|
|||
|
|
```javascript
|
|||
|
|
// Setup
|
|||
|
|
function compareEquality(a, b) {
|
|||
|
|
if (a === b) { // Change this line
|
|||
|
|
return "Equal";
|
|||
|
|
}
|
|||
|
|
return "Not Equal";
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
// Change this value to test
|
|||
|
|
compareEquality(10, "10");
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 代码说明
|
|||
|
|
|
|||
|
|
功能首先评估`if`条件`(a === b)`的计算结果为`true`同时考虑类型和值。如果是，则返回大括号之间的语句（“Equal”）。如果没有，则返回它们之外的下一个`return`语句（“Not equal”）。
