The Julia solution is amazing, it would be interesting to see more problems solved by Julia.

I didn’t realize the fortran community was so passionate haha

[ZippyMagician]

Personally, I would find a video on a more complicated challenge more interesting. Even if you can’t showcase as many languages, it would be better then a bunch of solutions that are just calling three simple functions. Possibly asking viewers to submit solutions in different languages could allow you to showcase more solutions for longer problems too.

Awesome work! Love the point free solution in Julia.

As a scientist, who has to optimize most of our HPC by hand, Fortran is my best friend! Python and Fortran the what the future looks like for scientific coding with Matlab pitching in here and there for a quick job or two. Fortran gets a bad rap because most of the people working on computers these days aren't engineers and scientists, they generally have no use for Fortran and find its structure a bit unattractive. Fortran's compiler, unlike c or cpp, which are heavily dependent on pointers, handles things in a simple and concise manner.
Oh and don't forget array handling! Fortran is probably the best language to handle arrays, especially with in-built bound checks. But the cake here is highly aggressive optimization, not aliasing pointers has its perks!!

At risk of adding five more characters to your Fortran code, you can add the word "pure" to the function (e.g., "pure integer function..."). This allows the compiler to knows it is supposed to be side-effect free, do appropriate checking, allow use in array expressions, and related optimizations. You'll have to do it with your gcd function as well.

I guess "tier lists" are better suited compared to "rankings" for comparisons like this.
Many of the compared languages were deemed nearly-identical, while being multiple ranks away from each other.

I’m absolutely thrilled to see FORTRAN covered here!! Love your content.

That point-free Julia solution sure looks nice with just two colors.

In the previous video I posted a comment with a very simple solution in hardware (Verilog), using the Euclid's method and I tested that on an FPGA. The resulting digital circuit only has an adder, a comparator and a register (all 32 bit).
I think it was marked as spam for some reason (perhaps because it included urls?).

Fortran now has GCD in the standard library.

[MarkFaldborg]

You love to see a community supporting newcomers, thanks fortran for being supportive!

Julia is such a special language. Pretty much my favorite high level language that has so many cool features

[MattKoski]

What do you use to animate the transitions between code blocks? I can't imagine you manually are animating where each character moves to, but I like the effect and would like to use it in future presentations I might do.

I think this is quickly becoming my favourite channel on YouTube

[EdouardTavinor]

Returning the result of the last expression in a block was used by lisp in 1960. I imagine Ruby gets it from there.

[rtdietrich]

Julia is amazing... and sooo fast. TX

[pikachu]

In Fortran, I think you don't need to mention the function's name in the last line, just `end function` would be enough.

Beautiful! How do you get syntax highlighting in PowerPoint?

[danielsmith]

There's two language "logos" I don't recognize. The lighthouse, and the geometric design with the B in the middle.
What are those languages?
