56533eb9ac21ba0edf2244dd	Selecting from Many Options with Switch Statements	1		从带有开关语句的多个选项中进行选择

Description

如果您有很多选择，请使用 switch 语句。 switch 语句测试一个值，并且可以包含许多定义各种可能值的 case 语句。从第一个匹配的 case 值开始执行语句，直到遇到 break 。这是 switch 语句的示例：

switch(lowercaseLetter) {
  case "a":
    console.log("A");
    break;
  case "b":
    console.log("B");
    break;
}

case 值以严格相等性（ === ）进行测试。 break 告诉JavaScript停止执行语句。如果省略 break ，将执行下一条语句。

Instructions

编写一个switch语句，测试val并设置以下条件的answer ：
1 - “alpha”
2 - “beta”
3 - “伽玛”
4 - “三角洲”

Tests

tests:
  - text: <code>caseInSwitch(1)</code>的值应为“alpha”
    testString: assert(caseInSwitch(1) === "alpha");
  - text: <code>caseInSwitch(2)</code>的值应为“beta”
    testString: assert(caseInSwitch(2) === "beta");
  - text: <code>caseInSwitch(3)</code>的值应为“gamma”
    testString: assert(caseInSwitch(3) === "gamma");
  - text: <code>caseInSwitch(4)</code>的值应为“delta”
    testString: assert(caseInSwitch(4) === "delta");
  - text: 您不应该使用任何<code>if</code>或<code>else</code>语句
    testString: assert(!/else/g.test(code) || !/if/g.test(code));
  - text: 你应该至少有3个<code>break</code>语句
    testString: assert(code.match(/break/g).length > 2);

Challenge Seed

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



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

// Change this value to test
caseInSwitch(1);
