I was looking for this kind of video. Thank you for your content.

In the sum case, in javascript you do not need the accumulator 0, since it will take the first value of the array instead.

Good video, thanks! One thing though - on import 17:06 the arity is specified with a colon not a comma, so should be "import MySuperSpecialProjectHelperModule, only: [myfunction: 1]. Additional functions would be separated with commas: "import MySuperSpecialProjectHelperModule, only: [myfunction: 1, another_function: 2]".

There's actually "===" in Elixir. Maybe it was a new addition but I want to know, does it do similar thing that "===" does in Javascript?

Phoenix vs express vs flask. I don't get why they say express, use a real framework to compare like Nestjs. Express, to me, is not a framework.

The website seems to be gone :( will it be back or is it gone for good?
