JSII3001: Type "Map" cannot be used as the return type because it is private or @internal

[Microos]

Why is Map not allowed in JSII? I got compile time error saying JSII3001: Type "Map" cannot be used as the return type because it is private or @internal for the following sample code

// index.ts

export class Tester {
    constructor() {}

    test(): Map<string, number> {
        return new Map<string, number>([['12', 12]]);
    }
}

The error further refer to the constructor of map:

  node_modules/jsii/node_modules/typescript/lib/lib.es2015.collection.d.ts:36:13
    36 declare var Map: MapConstructor;

Hi @Microos did you found a solution for that?

Hi, you simply cannot use Map while using JSII. Use the key value object as map instead.
