javascript - Typescript accessing variable with object full of specific objects with period (.) operator -


i have typescript interface 

interface bookstore {     books: { [key: string]: book } }

i can access single book it's name this

bookstore.books['onegoodbookname']

unfortunately i'm not able , internet hasn't been helping yet. ideas if can it?

var bs: bookstore; //... var book = <book>((<any>bs.books).onegoodbookname);

but in case loose type checks provided typescript:
