--description--

ifelse if语句中代码的执行顺序是很重要的。

在条件判断语句中,代码的执行顺序是从上到下,所以你需要考虑清楚先执行哪一句,后执行哪一句。

这有两个例子。

第一个例子:

function foo(x) {
  if (x < 1) {
    return "Less than one";
  } else if (x < 2) {
    return "Less than two";
  } else {
    return "Greater than or equal to two";
  }
}

第二个例子更改了代码的执行顺序:

function bar(x) {
  if (x < 2) {
    return "Less than two";
  } else if (x < 1) {
    return "Less than one";
  } else {
    return "Greater than or equal to two";
  }
}

这两个函数看起来几乎一模一样,我们传一个值进去看看它们有什么区别。

foo(0) // "Less than one"
bar(0) // "Less than two"

--instructions--

更改函数的逻辑顺序以便通过所有的测试用例。

--hints--

orderMyLogic(4)应该返回 "Less than 5"。

assert(orderMyLogic(4) === 'Less than 5');

orderMyLogic(6)应该返回 "Less than 10"。

assert(orderMyLogic(6) === 'Less than 10');

orderMyLogic(11)应该返回 "Greater than or equal to 10"。

assert(orderMyLogic(11) === 'Greater than or equal to 10');

--seed-contents--

function orderMyLogic(val) {
  if (val < 10) {
    return "Less than 10";
  } else if (val < 5) {
    return "Less than 5";
  } else {
    return "Greater than or equal to 10";
  }
}

orderMyLogic(7);

--solutions--

function orderMyLogic(val) {
  if(val < 5) {
    return "Less than 5";
  } else if (val < 10) {
    return "Less than 10";
  } else {
    return "Greater than or equal to 10";
  }
}
