For

The syntax for for loops is pretty simple. Just like in most languages with a for loop actually.

You’ll need an initialization statement (which is run once at the beginning), an expression to check if the for loop should continue, and finally an iterative expression (which is run at the end of every iteration.)

//       +------------------ Initial Statement
//       |        +--------- Check/Continue(?) Expression
//       |        |             +-- (Must Result in a Boolean)
//       |        |      +-- Iterative Expression
//       |        |      |
for (int i = 0; i < 30; i++) {
    io.writeln(i);
}

The output of the above code will be the numbers 0 through 29, each on a new line in the console.

Let’s say you want to iterate over elements in an array though, what then?
Combine the for loop with your array and the length() array method!

using std.io;

fn main() -> void {
    int[] my_arr = [35, 62, 84, 44, 27, 46, 85];
    for (int i = 0; i < my_arr.length(); i++) {
        io.writeln(my_arr[i]);
    }
}
