for

The for loop iterates over ranges of values or the items in a collection:

fn main() {
    for x in 1..5 {
        dbg!(x);
    }

    for elem in [2, 4, 8, 16, 32] {
        dbg!(elem);
    }
}

• Under the hood for loops use a concept called "iterators" to handle iterating over different kinds of ranges/collections. Iterators will be discussed in more detail later.
• Note that the first for loop only iterates to 4. Show the 1..=5 syntax for an inclusive range.
