Language Environments

Created Tuesday 27 May 2025

Some things to consider:

How it USUALLY works
Other ways it CAN work
(and how weird that is)

In a terminal as a REPL
In a terminal as a SCRIPT
Evoked as a SCRIPT

that's pretty much it

As a part of a WEB SERVER setup
PHP is invoked INSIDE OF HTML
and run WHEN YOU HIT THE WEBPAGE

Thus for development you can
just upload to the real server and hit reload

OR — run a local server and then deploy
OR use an online IDE (eww, but fine)

ALSO, Does have a REPL, but thats weird

client side,
As part of a WEB PAGE
Run BY THE BROWSER

So you can just open a browser and run it
(though macs are weird about this)

Also exists server side
So can do e.g. a REPL with node.js

Also, since it's literally the most popular language;
People are doing all sorts of weird things :)

Because its a GENERAL PURPOSE language,
Setup is similar to bash.
REPL or Save and Run, typically
