56533eb9ac21ba0edf2244d1	Comparison with the Strict Equality Operator	1		与严格平等算子的比较

Description

严格相等（ === ）是相等运算符（ == ）的对应物。但是，与尝试将两个值转换为常见类型的等式运算符不同，严格相等运算符不执行类型转换。如果要比较的值具有不同的类型，则认为它们不相等，并且严格相等运算符将返回false。例子

3 === 3 //是的
3 ==='3'//假

在第二个示例中， 3是Number类型， '3'是String类型。

Instructions

在if语句中使用strict equality运算符，因此当val严格等于7时，函数将返回“Equal”

Tests

tests:
  - text: <code>testStrict(10)</code>应返回“Not Equal”
    testString: assert(testStrict(10) === "Not Equal");
  - text: <code>testStrict(7)</code>应返回“Equal”
    testString: assert(testStrict(7) === "Equal");
  - text: <code>testStrict(&quot;7&quot;)</code>应返回“Not Equal”
    testString: assert(testStrict("7") === "Not Equal");
  - text: 您应该使用<code>===</code>运算符
    testString: assert(code.match(/(val\s*===\s*\d+)|(\d+\s*===\s*val)/g).length > 0);

Challenge Seed

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

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