I'm new to learning coding. Having a bit of a hard time with for loops and forEach. My code is not working for some reason, and I don't know what the error is. Does anyone see anything that I need to fix?

var myMovies = [

  {name: "Gladiator",
   rating: 5,
   seen: true
  },
  {name: "Vanilla Sky",
  rating: 4.5,
  seen: true
  },
  {name: "Beautiful Mind",
  rating: 5,
  seen:true
  },
  {name: "The Happytime Murders",
   rating: 3.5,
   seen: false
  }
];
  var movies = myMovies;
for(i = 0; i < 3; i ++)
  if(movies.seen){
  console.log("You have seen " + movies.name + "-" + movies.rating);
}else
console.log("You haven't seen " + movies.name + "-" + movies.rating);

Your problem is your myMovies and movies variables are arrays, you need to show which index you want. Here's your fixed code:

var myMovies = [

  {name: "Gladiator",
   rating: 5,
   seen: true
  },
  {name: "Vanilla Sky",
  rating: 4.5,
  seen: true
  },
  {name: "Beautiful Mind",
  rating: 5,
  seen:true
  },
  {name: "The Happytime Murders",
   rating: 3.5,
   seen: false
  }
];
var movies = myMovies;
for(i = 0; i < movies.length; i++) {
  if(movies[i].seen){
  console.log("You have seen " + movies[i].name + "-" + movies[i].rating);
}else
console.log("You haven't seen " + movies[i].name + "-" + movies[i].rating);

var myMovies = [

    {name: "Gladiator",
        rating: 5,
        seen: true
    },
    {name: "Vanilla Sky",
        rating: 4.5,
        seen: true
    },
    {name: "Beautiful Mind",
        rating: 5,
        seen:true
    },
    {name: "The Happytime Murders",
        rating: 3.5,
        seen: false
    }
];
var movies = myMovies;
for(i = 0; i < 4; i ++)
    if(movies[i].seen){
        console.log("You have seen " + movies[i].name + "-" + movies[i].rating);
    }else
        console.log("You haven't seen " + movies[i].name + "-" + movies[i].rating);

Or is it like this I think you are mixing for and foreach

var myMovies = [

    {name: "Gladiator",
        rating: 5,
        seen: true
    },
    {name: "Vanilla Sky",
        rating: 4.5,
        seen: true
    },
    {name: "Beautiful Mind",
        rating: 5,
        seen:true
    },
    {name: "The Happytime Murders",
        rating: 3.5,
        seen: false
    }
];

myMovies.forEach(movies=>{
    if(movies.seen){
        console.log("You have seen " + movies.name + "-" + movies.rating);
    }else
        console.log("You haven't seen " + movies.name + "-" + movies.rating);
})
