## Description

Empty code blocks can indicate incomplete implementation or may silently skip important operations. In control flow structures, this can lead to unexpected behavior or security vulnerabilities.

## Prevention

Prevention strategies for Empty Code Block based on 1 Shoulder detection rules.

### Node.js

Replace TODO/FIXME placeholder code with production implementations

## Warning Signs

- [LOW] Placeholder code at line ...: ...
- [LOW] TODO and FIXME comments indicating incomplete security implementations in production code

## Consequences

- Hide Activities
- DoS

## Mitigations

- Remove unnecessary empty blocks
- Add comments explaining why a block is intentionally empty
- Use static analysis to detect empty blocks

## Detection

- Total rules: 1
- Languages: javascript, typescript

## Rules by Language

### Javascript (1 rules)

- **AI-Generated Placeholder Code** [LOW]: Detects TODO and FIXME comments indicating incomplete security implementations in production code.
  - Remediation: Replace placeholder/mock values with production implementations.

### Typescript (1 rules)

- **AI-Generated Placeholder Code** [LOW]: Detects TODO and FIXME comments indicating incomplete security implementations in production code.
  - Remediation: Replace placeholder/mock values with production implementations.
