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.

Im Issue werden keine Implementierungsdateien, Tests oder Einstiegspunkte genannt. Beginne damit, zu prüfen, wie TypeScript wiederverwendbare Objekt-Index-Signaturtypen darstellt, und die verlinkte Diskussion in PR #26797 zu lesen; die Arbeit ist erst abgeschlossen, wenn das Projekt entscheidet, ob ein integrierter generischer string-schlüsselbasierter Typ in die Sprache gehört, und sein beabsichtigtes Verhalten festlegt.
