Safely convert object keys to camelCase recursively with circular reference protection, deep traversal, and robust error handling.
npm install camelcase-keys-safeSafely convert object keys to camelCase recursively with circular reference protection, deep traversal, and robust error handling.

//{ test1: 123, test2: { 'test3:': { testFour: 132 } } }

`$3
JavaScript
// Create an object with circular reference
const obj = { 'user-name': 'John', 'user-data': {} };
obj['user-data'].parent = obj; // Circular reference!// This would cause infinite loops with regular recursive functions
// But camelCaseSafe handles it gracefully
const safeResult = camelCaseSafe(obj);
console.log(safeResult);
// { userName: 'John', userData: { parent: [Circular] } }

Features
- ✅ Circular Reference Protection: Uses WeakMap caching to prevent infinite loops
- ✅ Deep Traversal: Recursively processes nested objects and arrays
- ✅ Type Safety: Preserves Date objects and other special types
- ✅ Array Support: Handles arrays containing objects
- ✅ Performance Optimized: Efficient caching mechanism
- ✅ Zero Dependencies: Only depends on
