Sample code

Count to 10

loop (10) {
  write(getLoopIndex() + 1);
}

What is getLoopIndex()

getLoopIndex() gets the current index inside the current loop loop (DOES NOT WORK FOR while LOOP!)

getLoopIndex(n) can get loop indexes outside of the current loop loop.

getLoopIndex(n = 0) is an abstraction for having to manage i, j, k, etc. because many beginners tend to mess this up, even though some interpreted languages (like Python) will let you have two for loops with i as the variable.

Example

loop(5) {
    loop(5) {
        write("i = " + getLoopIndex(1) + " j = " + getLoopIndex());
    }
}

Outputs:

i = 0 j = 0
i = 0 j = 1
i = 0 j = 2
i = 0 j = 3
i = 0 j = 4
i = 0 j = 5
i = 1 j = 0
i = 1 j = 1
i = 1 j = 2
i = 1 j = 3
etc.

All of that out of the way, here is another example

Fibonacci

a = double(0);
b = double(1);
c = double(0);
loop (50) {
  c = a + b;
  b = a;
  a = c;
  write(c);
}

Output:

1
1
2
3
5
...
