## 与小于算子的比较
|
|||
|
|
|
|||
|
|
**`<`** （Less Than）是一个逻辑运算符，它返回true，左边的值低于右边的值。
|
|||
|
|
|
|||
|
|
## 基本解决方案
|
|||
|
|
|
|||
|
|
```javascript
|
|||
|
|
function testLessThan(val) {
|
|||
|
|
if (val < 25)
|
|||
|
|
return "Under 25";
|
|||
|
|
|
|||
|
|
if (val < 55)
|
|||
|
|
return "Under 55";
|
|||
|
|
|
|||
|
|
return "55 or Over";
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
```
