String key-value type in basic types

typescript string key value type

Suggestion

Add an extra heavely used type - simple Object with string keys, used a lot as "primitive Map".
Tired writing { [ key: string ]: T } each time.
Want export type StrMap<T> = { [ key: string ]: T }; as one of basic types.
Keys in Objects are not too far from strings ( Object.keys(_object).join('/') ).
This is not fully related to https://github.com/microsoft/TypeScript/pull/26797 as it's a wider use case, IMHO.

Use Cases

I'm using this type in a numerous projects in numerous modules.

Examples

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Nell’issue non sono indicati file di implementazione, test o punti di ingresso. Inizia esaminando come TypeScript rappresenta i tipi riutilizzabili di firma dell’indice degli oggetti e la discussione collegata in PR #26797; il lavoro sarà completo solo quando il progetto deciderà se un tipo generico integrato indicizzato da stringhe appartiene al linguaggio e ne definirà il comportamento previsto.
