Expressions

Expressions in CFS are JavaScript‑like, with a smaller surface area.

Operators

count += 1;
total = price * qty;
done = count > 3 && ready;

Supported operators:

• Arithmetic: + - * / %
• Comparison: < <= > >=
• Equality: === !== (preferred), == != (still supported)
• Logic: && ||
• Nullish: ??

Ternary

label = count > 1 ? "Items" : "Item";

Nullish coalescing

title = name ?? "Untitled";

Notes

• Use === for strict equality to match JS expectations.
• Expressions can be used in bindings, assignments, and function calls.
