Using Object.values() in Stackblitz Angular Project

Question

In this stackblitz project we can use Object.values().

I'm trying to use it in this Angular project and it throws:

Property 'values' does not exist on type 'ObjectConstructor'.

I know that in general typescript projects via have to say that it's for a ES2017 environment specifically in TSConfig. Is there some setting in Stackblitz that can be flipped for this?

IIUC Angular should get Object.values from CoreJS.

I think you can manually add in your `tsconfig.json` at the `.angular-cli.json` level. — SiddAjmera, Sep 17 '18 at 16:49
It's `"lib": ["es2017"]` `in `tsconfig.json`, but I don't see it in `.angular-cli.json` ... — Ole, Sep 17 '18 at 16:54

I figured out that to fix that problem you can simply install typescript in stackblitz project dependencies. Just simply write:

npm i typescript

I had exacly the same error and now I have got fully working intellisense. Hope it helps!
