typescript - Property 'values' does not exist on type 'ObjectConstructor'

Question

In the following I am converting an enum in to an array, it seems that I may have something missing in my tsconfig.json.

This is the script:

const menuItems = Object.values(MediaListFilterType).map(value => ({
    type: value,
    description: () => {
        switch (value) {
            case value === MediaListFilterType.notPitched:
                return 'Exclude already pitched';
                break;
            case value === MediaListFilterType.notDoublePitched:
                return 'Exclude double pitched';
                break;
            case value === MediaListFilterType.assignedToMe:
                return 'Assigned to me';
                break;
            case value === MediaListFilterType.notAssigned:
                return 'Unassigned';
                break;
        }
    }
}));

this gives me this error: Property 'values' does not exist on type 'ObjectConstructor'.

and the tsconfig is as follows...

{
  "compilerOptions": {
    "module": "es6",
    "target": "es2015",
    "sourceMap": true,
    "jsx": "react",
    "moduleResolution": "node",
    "declaration": false,
    "allowSyntheticDefaultImports": true
  }
}

I am a bit new at this so I am not sure what I need to change in the tsconfig. Help!

Answer 1

add es2017.object to the compilerOptions.lib array in your tsconfig.json.
