typescript mode does not recognize /** @type {{[key: string]: string}} */

[thernstig]

Expected behavior

This should be valid (it is called an index signature https://www.typescriptlang.org/docs/handbook/2/objects.html#index-signatures).

/** @type {{[key: string]: string}} */
const obj = {};
obj.a = 'foo';
obj.b = 5;

Actual behavior

It is not as it gives the error Syntax error in type: {[key: string]: string}

ESLint Config

  "settings": {
    "jsdoc": {
      "mode": "typescript",
    }
  }

I am unsure if this should have been written at https://github.com/jsdoc-type-pratt-parser/jsdoc-type-pratt-parser/issues, because the repo hardly has any activity at all.

Environment

• Node version: v14.17.6
• ESLint version: v7.32.0
• eslint-plugin-jsdoc version: 36.1.0

jsdoc-type-pratt-parser has had activity, and this should indeed be filed there (though I suspect it is a dupe of jsdoc-type-pratt-parser/jsdoc-type-pratt-parser#96 ).

Closing, but feel free to comment further as needed.
