56533eb9ac21ba0edf2244df 在 Switch 语句添加多个相同选项 1 https://scrimba.com/c/cdBKWCV 18242 multiple-identical-options-in-switch-statements

--description--

如果你忘了给switch的每一条case添加break,那么直到遇见break为止,后续的case会一直执行。如果你想为多个不同的输入设置相同的结果,可以这样写:

switch(val) {
  case 1:
  case 2:
  case 3:
    result = "1, 2, or 3";
    break;
  case 4:
    result = "4 alone";
}

这样1、2、3 都会有相同的结果。

--instructions--

请写一个switch语句,根据输入的val的范围得出对应的answer
1-3 - "Low"
4-6 - "Mid"
7-9 - "High"

提示:
你的case应基于范围中的每一个数字编写。

--hints--

sequentialSizes(1)应该返回 "Low"。

assert(sequentialSizes(1) === 'Low');

sequentialSizes(2)应该返回 "Low"。

assert(sequentialSizes(2) === 'Low');

sequentialSizes(3)应该返回 "Low"。

assert(sequentialSizes(3) === 'Low');

sequentialSizes(4)应该返回 "Mid"。

assert(sequentialSizes(4) === 'Mid');

sequentialSizes(5)应该返回 "Mid"。

assert(sequentialSizes(5) === 'Mid');

sequentialSizes(6)应该返回 "Mid"。

assert(sequentialSizes(6) === 'Mid');

sequentialSizes(7)应该返回 "High"。

assert(sequentialSizes(7) === 'High');

sequentialSizes(8)应该返回 "High"。

assert(sequentialSizes(8) === 'High');

sequentialSizes(9)应该返回 "High"。

assert(sequentialSizes(9) === 'High');

你不应使用ifelse语句。

assert(!/else/g.test(code) || !/if/g.test(code));

你应该编写 9 个case语句。

assert(code.match(/case/g).length === 9);

--seed--

--seed-contents--

function sequentialSizes(val) {
  var answer = "";
  // Only change code below this line



  // Only change code above this line
  return answer;
}

sequentialSizes(1);

--solutions--

function sequentialSizes(val) {
  var answer = "";

  switch(val) {
    case 1:
    case 2:
    case 3:
      answer = "Low";
      break;
    case 4:
    case 5:
    case 6:
      answer = "Mid";
      break;
    case 7:
    case 8:
    case 9:
      answer = "High";
  }

  return answer;
}
