Syntax

JSL uses a syntax similar to c or java with semicolons as statement terminators. Unlike C or Java, it does not use braces ({}) to distinguish statement opening or closing blocks, but simply uses parentheses (()) based on the notion that "everything is an expression." Variable and function names are also case-insensitive in most contexts.

For example, JSL does not distinguish between a conditional-operator in an expression and an if statement, e.g.:

// comparable to this C code: result = (x==0) ? -1 : (x+1)
result = If(x==0, -1, x+1);

/* comparable to this C code:
     if(x<0) {
       x -= 3;
     } else if (x==0) {
       x = 0;
     } else {
       x += 3;
     } */
If(x<=0,
   x -= 3
   , /* implicit else if */ x==0,
   x = 0
   , /* implicit else clause */
   x += 3
);
