Using the for-loop is pretty helpful but as you’ve seen, it’s required a bunch of setup as well as management. Often times, you’ll have a list of items and you’ll just want to loop over it to use the current item.

var movies = ['Aliens', 'Interstellar', '2001', 'Event Horizon'];
for() {

}
for(var movie) {

}
for(var movie in) {

}
for(var movie in movies) {

}
for(var movie in movies) {
    print(movie);
}
var sentence = 'this space for rent';
for (var word in sentence) {
    print(word);
}
