noir-idioms

These guidelines help you write Noir programs that are readable, idiomatic, and produce efficient circuits.

Computing a value is often more expensive in a circuit than verifying a claimed value is correct. Use unconstrained functions to compute results off-circuit, then verify them with cheap constraints.

Note that the compiler already injects unconstrained helpers for some operations automatically (e.g., integer division). Don't hint what the compiler already optimizes — focus on higher-level computations like sorting, searching, and array construction where the compiler cannot automatically apply this pattern.
