56533eb9ac21ba0edf2244d9	Comparisons with the Logical Or Operator	1		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

tests:
  - text: 你应该使用<code>||</code>操作员一次
    testString: 'assert(code.match(/\|\|/g).length === 1, "You should use the <code>||</code> operator once");'
  - text: 你应该只有一个<code>if</code>语句
    testString: 'assert(code.match(/if/g).length === 1, "You should only have one <code>if</code> statement");'
  - text: <code>testLogicalOr(0)</code>应返回“Outside”
    testString: 'assert(testLogicalOr(0) === "Outside", "<code>testLogicalOr(0)</code> should return "Outside"");'
  - text: <code>testLogicalOr(9)</code>应返回“Outside”
    testString: 'assert(testLogicalOr(9) === "Outside", "<code>testLogicalOr(9)</code> should return "Outside"");'
  - text: <code>testLogicalOr(10)</code>应返回“Inside”
    testString: 'assert(testLogicalOr(10) === "Inside", "<code>testLogicalOr(10)</code> should return "Inside"");'
  - text: <code>testLogicalOr(15)</code>应返回“Inside”
    testString: 'assert(testLogicalOr(15) === "Inside", "<code>testLogicalOr(15)</code> should return "Inside"");'
  - text: <code>testLogicalOr(19)</code>应该返回“Inside”
    testString: 'assert(testLogicalOr(19) === "Inside", "<code>testLogicalOr(19)</code> should return "Inside"");'
  - text: <code>testLogicalOr(20)</code>应该返回“Inside”
    testString: 'assert(testLogicalOr(20) === "Inside", "<code>testLogicalOr(20)</code> should return "Inside"");'
  - text: <code>testLogicalOr(21)</code>应该返回“Outside”
    testString: 'assert(testLogicalOr(21) === "Outside", "<code>testLogicalOr(21)</code> should return "Outside"");'
  - text: <code>testLogicalOr(25)</code>应返回“Outside”
    testString: 'assert(testLogicalOr(25) === "Outside", "<code>testLogicalOr(25)</code> should return "Outside"");'

Challenge Seed

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);
