How to add SectionList 's sections in React Native from an array

I have an array of objects called movies (const movies = movie[]). A movie has the following properties:

  movie: {    name: string;    description: string;    date: Date;    duration: number  }

I want to use a RN SectionList component, making sections from the movie.date (Day):

**20 june 2020:**Movie name | description | durationMovie name | description | duration**18 april 2020:**Movie name | description | durationMovie name | description | duration...

How do I make the section and also how do I group my movies' array by date? I'm using lodash, but doing const groupedMovies = groupBy(movies, movie => movie.date); returns a collection and not an array.
