[CodeWars] 8kyu#3 - Get Planet Name By ID

■ Description:

The function is not returning the correct values. Can you figure out why?

getPlanetName(3); // should return 'Earth'

■ 문제

function getPlanetName(id){
  var name;
  switch(id){
    case 1:
      name = 'Mercury'
    case 2:
      name = 'Venus'
    case 3:
      name = 'Earth'
    case 4:
      name = 'Mars'
    case 5:
      name = 'Jupiter'
    case 6:
      name = 'Saturn'
    case 7:
      name = 'Uranus'
    case 8:
      name = 'Neptune'
  }
  
  return name;
}

■ 해결

:: break; 사용!

function getPlanetName(id){
  var name;
  switch(id){
    case 1:
      name = 'Mercury';
      break;
    case 2:
      name = 'Venus';
      break;
    case 3:
      name = 'Earth';
      break;
    case 4:
      name = 'Mars';
      break;
    case 5:
      name = 'Jupiter';
      break;
    case 6:
      name = 'Saturn';
      break;
    case 7:
      name = 'Uranus';
      break;
    case 8:
      name = 'Neptune';
      break;
  } 
  return name;
}
