Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

From ES6 to Scala: Basics
> I mean Scala because I guess it actually has it, but worth pointing out it's like 30 LOC to define one for JS, depending on how many convenience methods you want.
Here's one I wrote: https://github.com/sbernheim4/excoptional
I fully believe it to be one of the best Option implementations in JS/TS

[AskJS] How often do you use the ES6+(ES7, ES8, ES9 and ES10) syntax? Do you like it? Does it help?
https://github.com/sbernheim4/excoptional is an option object for js/ts

Functors, Applicatives, and Monads in Pictures
One benefit to keeping your value wrapped in a Maybe is that as you transform and manipulate the value and pass it around in your system, you leave it up to the last place in your system that uses the value to define the fallback value in the case of a None rather than defining a fallback value part way through and establish a convention that the fallback value means nothing was found at some other part of your system.
Another benefit to using Maybes is that you avoid the rigamarole of null checks at every call site where you want to use the value. If you have a function that returns null or a value, whenever you call that function you'll always have to add an if guard to validate it's not null. If it is, that function itself may return null, and callers to it will again have to implement the same check.
I wrote a JS implementation of the Option object and the readme has lots of specific examples about these benefits: https://github.com/sbernheim4/excoptional

CommandConsole: A shell written in C
I think an extensible shell like oh shell would be something I would prefer. Though it should not need closures on heap to extend (which is ridolous slow on arithmetic) and generate the data types at compilation time.

Bash functions are better than I thought
> Is there a reason we aren’t using a shell with a proper programming language for scripting?
Mostly because the people who want to introduce a "programming language" into the shell don't prioritize being a shell.
Check out the "Oh" shell for contrast. This is what a programming language looks like when you force it to conform to being a shell first priority.

This is "Scheme-like" but has FEXPRs so things can be redefined and evaluation can be controlled.

Thanks for showing me Oh! It really has f-exprs?! I didn't immediately see it in https://github.com/michaelmacinnis/oh/blob/main/doc/manual.m...
