localeTitle: 与逻辑或运算符的比较

## Description
逻辑OR运算符（ || ）返回true ，如果任一操作数为true 。否则，它返回false 。 逻辑或运算符由两个管道符号（ | ）组成。这通常可以在Backspace和Enter键之间找到。以下模式应该从以前的方法点看起来很熟悉： if（num> 10）{
返回“否”;
}
if（num <5）{
返回“否”;
}
返回“是”;
仅当num介于5和10之间（包括5和10）时，才会返回“Yes”。相同的逻辑可以写成： if（num> 10 || num <5）{
返回“否”;
}
返回“是”;
## Instructions
将两个if语句组合成一个语句，如果val不在10和20之间（包括10和20 ，则返回"Outside" 。否则，返回"Inside" 。
## Tests
```yml
tests:
- text: 你应该使用||操作员一次
testString: 'assert(code.match(/\|\|/g).length === 1, "You should use the || operator once");'
- text: 你应该只有一个if语句
testString: 'assert(code.match(/if/g).length === 1, "You should only have one if statement");'
- text: testLogicalOr(0)应返回“Outside”
testString: 'assert(testLogicalOr(0) === "Outside", "testLogicalOr(0) should return "Outside"");'
- text: testLogicalOr(9)应返回“Outside”
testString: 'assert(testLogicalOr(9) === "Outside", "testLogicalOr(9) should return "Outside"");'
- text: testLogicalOr(10)应返回“Inside”
testString: 'assert(testLogicalOr(10) === "Inside", "testLogicalOr(10) should return "Inside"");'
- text: testLogicalOr(15)应返回“Inside”
testString: 'assert(testLogicalOr(15) === "Inside", "testLogicalOr(15) should return "Inside"");'
- text: testLogicalOr(19)应该返回“Inside”
testString: 'assert(testLogicalOr(19) === "Inside", "testLogicalOr(19) should return "Inside"");'
- text: testLogicalOr(20)应该返回“Inside”
testString: 'assert(testLogicalOr(20) === "Inside", "testLogicalOr(20) should return "Inside"");'
- text: testLogicalOr(21)应该返回“Outside”
testString: 'assert(testLogicalOr(21) === "Outside", "testLogicalOr(21) should return "Outside"");'
- text: testLogicalOr(25)应返回“Outside”
testString: 'assert(testLogicalOr(25) === "Outside", "testLogicalOr(25) should return "Outside"");'
```
## Challenge Seed
```js
function testLogicalOr(val) {
// Only change code below this line
if (val) {
return "Outside";
}
if (val) {
return "Outside";
}
// Only change code above this line
return "Inside";
}
// Change this value to test
testLogicalOr(15);
```
