Conditional Statements

Syntactically, a conditional statement requires the following elements:

1. if keyword

2. In braces, code block of first option

3. else keyword

4. In braces, code block of second option

5. Terminating ;

(Note further that ifand else are always paired—there is no standalone if.)

Branching Statements

Besides simple conditional statements, Jock supplies a type-based dispatch statement, match, and a value-based dispatch statement, switch.
