EXAMPLE:
for (var movie of movies) {
if (movie.status === 'available') {
console.log("The movie " + movie.title + " plays at " + movie.time);
}
}
Why not:
if (movie.status === 'available') {
console.log("The movie " + movie.title + " plays at " + movie.time);
}
}

Without the for loop you would have to enter each item one by one into the conditional statement. The for loop allows you to loop through the items in the object and apply the conditional statement to each one separately.

7,739 PointsIt's using a for Each loop to loop through all the props in the object. It quite literally reads: For Each movie inside of the object movies > checks condition > console.log(whatever info here);
It needs to loop so you can console.log them all in one go instead of manually copying and pasting what you wrote below, for each movie property inside of the object.
Hope this clears it up a bit!
