Count branch decisions and maximum decision nesting for the program and each function.
Submit the example or replace it with your own input. Source is parsed but never executed.
Explicit static behavior
Each scope starts at one path, then adds branches for conditionals, loops, catches, tested switch cases, ternaries, and short-circuit logical operators.

Nested functions are measured independently and excluded from their parent's count. The metric is a review aid, not a quality verdict.
Tool Swim parses source as standard ECMAScript inside a disposable Web Worker with a 2,000 ms deadline. It never calls eval, Function, imported modules, or user code.
Source and results stay in the current browser tab. The public tool makes no API request, stores no preset, and does not require an account or telemetry.
