Trying to use destructuring inside the Movie.create() method

I added a helper function to accept the different pieces of data for each movie in order to make the code look more clean. I'm trying to utilize the destructuring shorthand like this:

const createMovie = (title, runtime, releaseDate, availableOnVHS) => {
  return Movie.create({
    { title },
    { runtime },
    { releaseDate },
    { availableOnVHS },
  })
}

This renders the following error:

/Users/.../sql-orms-with-node/app.js:8
    { title },
    ^

SyntaxError: Unexpected token '{'

When I run the code as follows, it works:

const createMovie = (title, runtime, releaseDate, availableOnVHS) => {
  return Movie.create({
    title: title,
    runtime: runtime,
    releaseDate: releaseDate,
    availableOnVHS: availableOnVHS,
  })
}

Is there a way I can use the destructuring assignment for the createMovie function?

Thanks!

This isn't a case for restructuring, but you can use the shorthand for creating an object literal:

const createMovie = (title, runtime, releaseDate, availableOnVHS) =>
    Movie.create({title, runtime, releaseDate, availableOnVHS});

Okay thanks! So when creating an object literal, if I don't provide a key value pairβ€”just title for example, it will automatically be interpreted as title: title? I guess I thought that was an example of restructuring, my bad.
