Brandon helped me out with this one.

Switch statements clean up your code when you’re checking if a variable matches a value. Say if you’re looking to check if the variable direction is valid.

Bad way

if ( direction === 'north' || direction === 'south' || direction === 'east' || direction === 'west' ) {
	console.log('valid direction: ' + direction);
} else {	
    console.log('invalid direction');
}

Better way with a switch statement

switch ( direction ) {
  case 'north' : case 'south' : case 'east' : case 'west' : 
    console.log('valid direction: ' + direction);
    break;
  default :
    console.log('invalid direction');
}
