Switch Statement
Switch statements (sometimes known as Select statements) also work very similar
to if statements. Instead of a condition, you supply a switch statement with
a single variable and define different blocks of code to run depending on the value
of that variable. Most languages allow you to supply a default action, meaning
how the switch statement would handle a value that you did not explicitly define
code to handle.
Break Keyword:
Used to exit any loop or switch statement. Most languages use this keyword
at the end
of each block of code that you have associated a value with. Without
this keyword, most switch statements will execute all blocks of code following the
value it started from.
Examples:
var Card = new Object();
Card.FaceValue = "A";
Card.NumberValue = 1;
Card.Name = "Ace";
Card.Suit = "Spades";
switch(Card.Suit)
{
case "Clubs":
case "Spades":
Card.Color = "Black";
break;
case "Diamonds":
case "Hearts":
Card.Color = "Red";
break;
