56533eb9ac21ba0edf2244de	Adding a Default Option in Switch Statements	1	https://www.freecodecamp.org/guide/certificates/adding-a-default-option-in-switch-statements

Description

In a switch statement you may not be able to specify all possible values as case statements. Instead, you can add the default statement which will be executed if no matching case statements are found. Think of it like the final else statement in an if/else chain. A default statement should be the last case.

switch (num) {
  case value1:
    statement1;
    break;
  case value2:
    statement2;
    break;
...
  default:
    defaultStatement;
    break;
}

Instructions

Write a switch statement to set answer for the following conditions:
"a" - "apple"
"b" - "bird"
"c" - "cat"
default - "stuff"

Tests

tests:
  - text: <code>switchOfStuff("a")</code> should have a value of "apple"
    testString: 'assert(switchOfStuff("a") === "apple", "<code>switchOfStuff("a")</code> should have a value of "apple"");'
  - text: <code>switchOfStuff("b")</code> should have a value of "bird"
    testString: 'assert(switchOfStuff("b") === "bird", "<code>switchOfStuff("b")</code> should have a value of "bird"");'
  - text: <code>switchOfStuff("c")</code> should have a value of "cat"
    testString: 'assert(switchOfStuff("c") === "cat", "<code>switchOfStuff("c")</code> should have a value of "cat"");'
  - text: <code>switchOfStuff("d")</code> should have a value of "stuff"
    testString: 'assert(switchOfStuff("d") === "stuff", "<code>switchOfStuff("d")</code> should have a value of "stuff"");'
  - text: <code>switchOfStuff(4)</code> should have a value of "stuff"
    testString: 'assert(switchOfStuff(4) === "stuff", "<code>switchOfStuff(4)</code> should have a value of "stuff"");'
  - text: You should not use any <code>if</code> or <code>else</code> statements
    testString: 'assert(!/else/g.test(code) || !/if/g.test(code), "You should not use any <code>if</code> or <code>else</code> statements");'
  - text: You should use a <code>default</code> statement
    testString: 'assert(switchOfStuff("string-to-trigger-default-case") === "stuff", "You should use a <code>default</code> statement");'
  - text: You should have at least 3 <code>break</code> statements
    testString: 'assert(code.match(/break/g).length > 2, "You should have at least 3 <code>break</code> statements");'

Challenge Seed

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



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

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

Solution

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

  switch(val) {
    case "a":
      answer = "apple";
      break;
    case "b":
      answer = "bird";
      break;
    case "c":
      answer = "cat";
      break;
    default:
      answer = "stuff";
  }
  return answer;
}
