Lesson: Replacing If Else Chains with Switch

If you have many options to choose from, a switch statement can be easier to write than many chained if/if else 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";
}
