localeTitle: 与小于或等于运算符的比较
---
## Description
less than or equal to运算符（ <= ）比较两个数字的值。如果左边的数字小于或等于右边的数字，则返回true 。如果左侧的数字大于右侧的数字，则返回false 。与等于运算符一样， less than or equal to转换数据类型。 例子 4 <= 5 //是的
'7'<= 7 //是的
5 <= 5 //是的
3 <= 2 //假
'8'<= 4 //假
## Instructions
将less than or equal to运算符添加到指示的行，以便返回语句有意义。
## Tests
```yml
tests:
- text: testLessOrEqual(0)应该返回“小于或等于12”
testString: 'assert(testLessOrEqual(0) === "Smaller Than or Equal to 12", "testLessOrEqual(0) should return "Smaller Than or Equal to 12"");'
- text: testLessOrEqual(11)应返回“小于或等于12”
testString: 'assert(testLessOrEqual(11) === "Smaller Than or Equal to 12", "testLessOrEqual(11) should return "Smaller Than or Equal to 12"");'
- text: testLessOrEqual(12)应返回“小于或等于12”
testString: 'assert(testLessOrEqual(12) === "Smaller Than or Equal to 12", "testLessOrEqual(12) should return "Smaller Than or Equal to 12"");'
- text: testLessOrEqual(23)应返回“小于或等于24”
testString: 'assert(testLessOrEqual(23) === "Smaller Than or Equal to 24", "testLessOrEqual(23) should return "Smaller Than or Equal to 24"");'
- text: testLessOrEqual(24)应返回“小于或等于24”
testString: 'assert(testLessOrEqual(24) === "Smaller Than or Equal to 24", "testLessOrEqual(24) should return "Smaller Than or Equal to 24"");'
- text: testLessOrEqual(25)应该返回“超过24”
testString: 'assert(testLessOrEqual(25) === "More Than 24", "testLessOrEqual(25) should return "More Than 24"");'
- text: testLessOrEqual(55)应该返回“超过24”
testString: 'assert(testLessOrEqual(55) === "More Than 24", "testLessOrEqual(55) should return "More Than 24"");'
- text: 你应该至少使用<=运算符两次
testString: 'assert(code.match(/val\s*<=\s*("|")*\d+("|")*/g).length > 1, "You should use the <= operator at least twice");'
```
## Challenge Seed
```js
function testLessOrEqual(val) {
if (val) { // Change this line
return "Smaller Than or Equal to 12";
}
if (val) { // Change this line
return "Smaller Than or Equal to 24";
}
return "More Than 24";
}
// Change this value to test
testLessOrEqual(10);
```
