56533eb9ac21ba0edf2244d2	Comparison with the Inequality Operator	1		与不等式算子的比较

Description

不等运算符（ != ）与等于运算符相反。它意味着“不等于”并返回false ，其中相等性将返回true ， 反之亦然 。与等式运算符一样，不等式运算符将在比较时转换数据类型的值。例子

1！= 2 //是的
1！=“1”//假
1！='1'//假
1！= true // false
0！= false // false

Instructions

在if语句中添加不等式运算符!= ，以便当val不等于99时函数将返回“Not Equal”

Tests

tests:
  - text: <code>testNotEqual(99)</code>应返回“Equal”
    testString: 'assert(testNotEqual(99) === "Equal", "<code>testNotEqual(99)</code> should return "Equal"");'
  - text: <code>testNotEqual(&quot;99&quot;)</code>应该返回“Equal”
    testString: 'assert(testNotEqual("99") === "Equal", "<code>testNotEqual("99")</code> should return "Equal"");'
  - text: <code>testNotEqual(12)</code>应该返回“Not Equal”
    testString: 'assert(testNotEqual(12) === "Not Equal", "<code>testNotEqual(12)</code> should return "Not Equal"");'
  - text: <code>testNotEqual(&quot;12&quot;)</code>应该返回“Not Equal”
    testString: 'assert(testNotEqual("12") === "Not Equal", "<code>testNotEqual("12")</code> should return "Not Equal"");'
  - text: <code>testNotEqual(&quot;bob&quot;)</code>应返回“Not Equal”
    testString: 'assert(testNotEqual("bob") === "Not Equal", "<code>testNotEqual("bob")</code> should return "Not Equal"");'
  - text: 你应该使用<code>!=</code>运算符
    testString: 'assert(code.match(/(?!!==)!=/), "You should use the <code>!=</code> operator");'

Challenge Seed

// Setup
function testNotEqual(val) {
  if (val) { // Change this line
    return "Not Equal";
  }
  return "Equal";
}

// Change this value to test
testNotEqual(10);
