Finding the length of an index is obviously pretty trivial. But there are several ways to do find it, and there are some “gotchas” if you aren’t careful. The IndexLength function is, of course, the recommended and reliable way to get it. But are you in the habit of using
Size(I)? Did you know that
Size(I) is not the same as
IndexLength(I), and is not always the length of the index? Watch the video to understand the differences.
