seamless-immutable provides Immutable data structures for JavaScript that are designed for simplicity and performance. This library ensures that once created, the data structure cannot be modified directly, preventing unintended side effects and making state management more predictable. It's compatible with standard JavaScript arrays and objects, allowing easy integration. Data structures are updated through methods that return new, modified versions, leaving the original untouched. It is optimized for speed and is an excellent choice for React and Redux applications.
