56533eb9ac21ba0edf2244d3 严格不等运算符 1 https://scrimba.com/c/cKekkUy 16791 comparison-with-the-strict-inequality-operator

--description--

严格不相等运算符(!==)与全等运算符是相反的。这意味着严格不相等并返回false的地方,用严格相等运算符会返回true反之亦然。严格不相等运算符不会转换值的数据类型。

示例

3 !==  3   // false
3 !== '3'  // true
4 !==  3   // true

--instructions--

if语句中,添加严格不相等运算符!==,这样如果val17严格不相等的时候,函数会返回 "Not Equal"。

--hints--

testStrictNotEqual(17)应该返回 "Equal"。

assert(testStrictNotEqual(17) === 'Equal');

testStrictNotEqual("17")应该返回 "Not Equal"。

assert(testStrictNotEqual('17') === 'Not Equal');

testStrictNotEqual(12)应该返回 "Not Equal"。

assert(testStrictNotEqual(12) === 'Not Equal');

testStrictNotEqual("bob")应该返回 "Not Equal"。

assert(testStrictNotEqual('bob') === 'Not Equal');

应该使用 !== 运算符。

assert(code.match(/(val\s*!==\s*\d+)|(\d+\s*!==\s*val)/g).length > 0);

--seed--

--seed-contents--

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

testStrictNotEqual(10);

--solutions--

function testStrictNotEqual(val) {
  if (val !== 17) {
    return "Not Equal";
  }
  return "Equal";
}
