Don't use TypeScript types like this. Use Map Pattern instead

TLDR While working on a real-life project, the author encountered a TypeScript implementation that lacked flexibility. They improved the design using the Map pattern, which reduced redundancy and potential errors by allowing dynamic additions. Further, stricter controls were applied to ensure only predefined reactions can be added. This approach balances flexibility and control, enhancing code maintainability.

When To Use the ?? And ||

TLDR The ?? (nullish coalescing) and || (logical OR) operators in JavaScript provide default values when the left-hand side expression is not provided. The ?? operator only checks for null and undefined, allowing other falsy values like 0, false, or an empty string to remain. The || operator checks for all falsy values. The ?? operator is particularly useful for APIs, optional parameters, or dynamic data that may not always be defined.
