Pascal has a lot of influence on this, but Go as well! My PL friends often talk about Go's benefits and flaws when thinking about advancing other their own projects or improving the mainstream languages they work on.
Go changed something, not sure if 20 or 21, where it will download the Go compiler of all your third-party which don’t match yours. It slows things down.
I would add that Delphi still follows along, enough for an yearly conference in Germany, and that C# since getting Native AOT and the low level programming improvements, is close enough to Modula-3 design.
There is Swift as well, although quite far from Wirthian compile times.
Even C has one, regardless of how tiny it happens to be, or the possibility of freestanding deployment.
In compiler speak, a runtime provides all infrastructure required by the language for program startup, shutdown, infrastructure for the standard library execution.
The infrastructure required to support a programming language, startup and shutdown boilerplate, all the required functionality to support standard library features including integration points between language semantics and support code.
Stuff like what code runs before and after main(), trap handlers for floating point arithmetic, handling of thread local storage, bind language heap handling primitives to library code, traps for handling stack overflow errors,....
Right, runtime is so broad that it's hard to say something has "no runtime". libgcc + your choice of crt0 is a C runtime, and the JVM is a Java runtime. That's a huge spectrum.
It's worth being charitable in your interpretation though and recognising "no runtime" probably refers to JVM-shaped or Node-shaped things, not libgcc+crt0-shaped things.
Alternatively, "runtime" is a derogatory term used by programmers who want to show superiority over others who use languages with more (built-in) features than theirs.
There's practically no difference for the overwhelming majority of software these days. Most people aren't working on embedded systems or operating systems.
