How Do I Make Emacs Have IDE-Like Indentation On The Fly?
I might be misunderstanding, but would something like EditorConfig help? I have found it does a really good job of configuring indentation behavior for projects that use EditorConfig.

Emacs 29 is nigh What can we expect?
For #2, I've been pretty happy with dtrt-indent (https://github.com/jscheid/dtrt-indent) for DWIM indentation bouncing between projects.
I have yet to try apheleia, but I wouldn't be surprised if just enabling apheleia, dtrt-indent, and editorconfig-mode (https://github.com/editorconfig/editorconfig-emacs) in prog-mode-hook just did what you wanted.

Eglot has landed on master: Emacs now has a built-in LSP client
> My only complaint is that I can never get Emacs's indentation to match what Prettier wants to do, so I'll type a bunch of code, prettier-on-save, and everything gets moved around.
I had this same issue, and it was annoying enough I continued to use https://github.com/editorconfig/editorconfig-emacs alongside prettier.
This does create another annoyance in having to configure editorconfig for new projects instead of relying on prettier alone.

Is there a package or command out there that can add a newline at the end of the file if it doesn't exist?

Editorconfig and tabs/spaces
According to the repo you should only need to enable (editorconfig-mode 1) in the init, but there's also a troubleshooting section that might help out for your specific situation. Hope that helps!

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).

The parser we wrote transforms the GraphQL AST into ESTree structure, so it allows you to travel the GraphQL AST tree easily.
