What problem does it solve?
Index signatures are imprecise and can lead to typos, weak autocomplete, and unsafe access. This skill guides developers to replace permissive index signatures with interfaces, Records, or Maps for known keys, enhancing type safety.
Core Features & Use Cases
- Encourages replacing dynamic key maps with precise types (Interface, Record, or Map).
- Demonstrates concrete usage patterns for modeling API shapes, configuration schemas, and data from CSV/JSON with strong typing.
- Provides guidelines on when to apply index signatures only for truly additional properties.
Quick Start
Refactor an example object from an index signature to a typed interface for known keys, and migrate truly dynamic keys to a Map for safer access.
