--description--

使用大于等于运算符(>=)来比较两个数字的大小。如果大于等于运算符左边的数字比右边的数字大或者相等,它会返回true。否则,它会返回false

与相等运算符相似,大于等于运算符在比较的时候会转换值的数据类型。

例如

6   >=  6   // true
7   >= '3'  // true
2   >=  3   // false
'7' >=  9   // false

--instructions--

添加大于等于运算符到指定行,使得函数的返回语句有意义。

--hints--

testGreaterOrEqual(0)应该返回 "Less than 10"。

assert(testGreaterOrEqual(0) === 'Less than 10');

testGreaterOrEqual(9)应该返回 "Less than 10"。

assert(testGreaterOrEqual(9) === 'Less than 10');

testGreaterOrEqual(10)应该返回 "10 or Over"。

assert(testGreaterOrEqual(10) === '10 or Over');

testGreaterOrEqual(11)应该返回 "10 or Over"。

assert(testGreaterOrEqual(11) === '10 or Over');

testGreaterOrEqual(19)应该返回 "10 or Over"。

assert(testGreaterOrEqual(19) === '10 or Over');

testGreaterOrEqual(100)应该返回 "20 or Over"。

assert(testGreaterOrEqual(100) === '20 or Over');

testGreaterOrEqual(21)应该返回 "20 or Over"。

assert(testGreaterOrEqual(21) === '20 or Over');

你应该使用>=运算符至少两次。

assert(code.match(/val\s*>=\s*('|")*\d+('|")*/g).length > 1);

--seed--

--seed-contents--

function testGreaterOrEqual(val) {
  if (val) {  // Change this line
    return "20 or Over";
  }

  if (val) {  // Change this line
    return "10 or Over";
  }

  return "Less than 10";
}

testGreaterOrEqual(10);

--solutions--

function testGreaterOrEqual(val) {
  if (val >= 20) {  // Change this line
    return "20 or Over";
  }

  if (val >= 10) {  // Change this line
    return "10 or Over";
  }

  return "Less than 10";
}
