Switch
switch compares a given value with sets of other values. Depending on which set it is found in, the corresponding block of instructions will be executed.
switch x
(1 2 3) {
std.println "bad";
} (4 5 6) {
std.println "mediocre";
} (7 8 9) {
std.println "good";
} (10) {
std.println "perfect";
};
If the value is not found in any set, no blocks will be executed. It is a good practice to add a default block, which gets executed in those cases.
switch x
(2 3 5 7 11 13 17 19) {
std.println "prime number";
} (0 1 4 9 16) {
std.println "square number";
} (6) {
std.println "perfect number";
} {
std.println "uninteresting number";
};
