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.

ESLint Understand By Doing Part 1: Abstract Syntax Trees
ESLint's AST format, ESTree, would represent this line of code as:

Eglot has landed on master: Emacs now has a built-in LSP client
That was a super interesting link, thank you.
For the ontological problem, I presume you're referring to how there are so many differing ideas of how to represent ASTs (apologies for mixing languages, these URLs were just handy):
* https://lisperator.net/uglifyjs/ast#nodes
* https://github.com/estree/estree#the-estree-spec
* ... likely others
which makes it hard for ls1 to ask ls2 about "the for-of iteration variable Node" because ls2 could be using UglifyJS or ESTree or their own(!) AST nomenclature?
And all of this is made worse by (e.g.) Java1.3 versus Java19 because languages are rarely static

Statements vs. Expressions
I find it better to actually look at the AST for javascript.
These are expressions:

These are statements:
https://github.com/estree/estree/blob/master/es5.md#statemen...
I guess the confusing part for many is how an expression can also be a statement. But if you look at the ExpressionStatement you see that an expression is not also a statement. It's just the wrapper statement!

A technical tale of NodeSecure - Chapter 2
When I started the NodeSecure project I had almost no experience 🐤 with AST (Abstract Syntax Tree). My first time was on the SlimIO project to generate codes dynamically with the astring package (and I had also looked at the ESTree specification).
