JavaScript Patterns 2.6 switch Pattern

Principle

? Aligning each case with switch(an exception to the curly braces indentation
rule).

? Indenting the code within each case.

? Ending each case with a clear break;.

? Avoiding fall-throughs (when you omit the break intentionally). If you‘re
absolutely convinced that a fall-through is the best approach, make sure you
document such cases, because they might look like errors to the readers of your
code.

? Ending the switch with a default: to make sure there‘s always a sane result
even if none of the cases matched.

var inspect_me = 0,

result = ‘‘;

switch (inspect_me) {

   case 0:

      result = "zero";

      break;

   case 1:

      result = "one";

      break;

   default:

      result = "unknown";

}
