Function modifyLibrary

Parameters

• baseLibrary: LibraryData

  the library to be modified

• newData: {
      [key: string]: string | string[];
  }

  key-value pairs with which to update the library

  • [key: string]: string | string[]

• Optional category: string

  the category that the new values should go into. This isn't necessary if we're modifying the value of a key that already exists in the library; modifyLibrary will figure it out. It's only necessary if we're adding a new key.
