You can create switch expressions using the keywords switch,
case and default. They evaluate the literals and
return a value when a literal matches the switch expression, and can return a default
value if none of the literals match the expression. You can specify multiple expressions
for the same case, separated by , or ;. In this case,
all expressions are evaluated if the condition is met, and the result of the last
expression is returned.
These expressions should follow this syntax:
switch (expression1) {
case literal1: expression2, expression3
case literal2: expression4, expression5
default: expression6
}The following example is a valid switch
expression:
switch (media) {
case "Star Wars": message = "May the Force be with you"
case "Star Trek": message = "Live long and prosper"
default: "Cheers"
}
