**Search Terms:** Documentation **Typescript Version:** 3.5.3 Documentation [here](http://www.typescriptlang.org/docs/handbook/release-notes/typescript-1-8.html#augmenting-globalmodule-scope-from-modules) and [here](http://www.typescriptlang.org/docs/handbook/declaration-merging.html#global-augmentation) mention, "Neither module augmentations nor global augmentations can add new items to the top level scope - they can only “patch” existing declarations.", however I am able to "add new items". ``` //file-a.ts import * as moment from 'moment'; declare module "moment" { interface GoblyGoop { name: string; } } let y: moment.GoblyGoop; //file-b.ts import * as moment from 'moment'; let y: moment.GoblyGoop; ```
