Exercises: Objects as Arguments

The Movie Database

It's like IMDB, but much much smaller!

• Create an object to store the following information about your favorite movie: title (a string), duration (a number), and stars (an array of strings).
• Create a function to print out the movie information like so: "Puff the Magic Dragon lasts for 30 minutes. Stars: Puff, Jackie, Living Sneezes."

See Solution

var myFavMovie = {
    title: 'Puff the Magic Dragon',
    duration: 30,
    stars: ['Puff', 'Jackie', 'Living Sneezes']
};

function printMovie(movie) {
    console.log(movie.title + ' lasts for ' + movie.duration + ' minutes');
    var starsString = 'Stars: ';
    for (var i = 0; i < movie.stars.length; i++) {
        starsString += movie.stars[i];
        if (i != movie.stars.length -1) {
            starsString += ', ';
        }
    }
    console.log(starsString);
}

// Or...
function printMovie(movie) {
    console.log(movie.title + ' lasts for ' + movie.duration + ' minutes');
    console.log('It stars ' + movie.stars.join(', '));
}
printMovie(myFavMovie);
