MERN => Mongo, Express, React, NodeJS. Which is an evolution (as far as I can tell on) MEAN => Mongo, Express, Angular, NodeJS.

But really, NodeJS is unnecessary in the acronym, but is used to make a backronym. Really - how do you run Express without NodeJS? Maybe it’s so the backronym wasn’t “MAN”.

Also interesting in comparison to older forms of this style of stack description:

* LAMP - Linux Apache MySQL PHP/Python/Perl

* LEPP - Linux Nginx PostgreSQL PHP/Python/Perl

MEAN and MERN do not specify the OS and swap more open ended possibilities for specific frameworks. I guess LEMJ doesn't roll off the tongue very well.

And while this was submitted with MERN in the title, the README omits Express but mentions Socket.io.
