Disallow try/catch blocks where the try body contains no code that can throw

Category: Dead Code | Tier: Pro

Why This Matters

AI wraps safe operations in try/catch blocks defensively. When the try block cannot throw, the catch block is dead code that misleads readers into thinking the operation is risky and adds unnecessary complexity.

Bad Code

// Catch block can never execute -- JSON.stringify doesn't throw
try {
  const str = JSON.stringify({ name: 'test' });
} catch (error) {
  console.error('Failed to stringify', error);
}

Good Code

// Only wrap operations that can actually throw
const str = JSON.stringify({ name: 'test' });

// Use try/catch for operations that genuinely fail
try {
  const data = JSON.parse(userInput);
} catch (error) {
  console.error('Invalid JSON input', error);
}
