Programmers love to sneer at the world of fashion where trends blow through like breezes. Skirt lengths rise and fall, pigments come and go, ties get fatter, then thinner. But in the world of technology, rigor, science, math, and precision rule over fad.

The new technologies that deliver one or more of these eclipse the previous generation. It’s a meritocracy, not a whimsy-ocracy.

What follows is a list of what’s hot and what’s not among today’s programmers. Not everyone will agree with what’s A-listed, what’s D-listed, and what’s been left out. That’s what makes programming an endlessly fascinating profession: rapid change, passionate debate, sudden comebacks.

Not: Full language stacks

It wasn’t long ago that people who created a new programming language had to build everything that turned code into the bits fed to the silicon.
