Same as why you need MySQL in the LAMP stack ... you could do the same using PHP and, say, Postgres on Windows using nginx.
What qualifies as a cool stack is the following:
- One tech each for the DB (Mongo / MySQL), web server (Apache / Express), environment (Node / Linux), and the defining framework or language (React / Angular / PHP).
- You should be able to pronounce the acronym, for example, LNMP is no good.
- It's actually something. You can be Mean, light a Lamp or go for a vacation to Mern.
