--description--

If you have many options to choose from, a switch statement can be easier to write than many chained if/else if statements. The following:

if (val === 1) {
  answer = "a";
} else if (val === 2) {
  answer = "b";
} else {
  answer = "c";
}

can be replaced with:

switch (val) {
  case 1:
    answer = "a";
    break;
  case 2:
    answer = "b";
    break;
  default:
    answer = "c";
}

--instructions--

Change the chained if/else if statements into a switch statement.

--hints--

You should not use any else statements anywhere in the editor

assert(!/else/g.test(__helpers.removeJSComments(code)));

You should not use any if statements anywhere in the editor

assert(!/if/g.test(__helpers.removeJSComments(code)));

You should have at least four break statements

assert(__helpers.removeJSComments(code).match(/break/g).length >= 4);

chainToSwitch("bob") should return the string Marley

assert(chainToSwitch('bob') === 'Marley');

chainToSwitch(42) should return the string The Answer

assert(chainToSwitch(42) === 'The Answer');

chainToSwitch(1) should return the string There is no #1

assert(chainToSwitch(1) === 'There is no #1');

chainToSwitch(99) should return the string Missed me by this much!

assert(chainToSwitch(99) === 'Missed me by this much!');

chainToSwitch(7) should return the string Ate Nine

assert(chainToSwitch(7) === 'Ate Nine');

chainToSwitch("John") should return "" (empty string)

assert(chainToSwitch('John') === '');

chainToSwitch(156) should return "" (empty string)

assert(chainToSwitch(156) === '');
