What I'd like to suggest is that both of these assume the need for there to be some kind of 'low-level API' either to operate the machine or to perform the observable effects. Generally, execution semantics involves a process of reading language text and arriving at either a description of an abstract machine or a description of observable side effects. Now, let's dig into execution semantics a bit.

all take in JavaScript text and output some kind of analytical product, highlighted text e.g., which is influenced by the execution semantics, but not actually representative of it.

Linters, highlighters, type checkers, etc.

The difference is thus a little subjective, but usually one thinks of a compiler as outputting very low level code and a transpiler as outputting high level code. Transpilers are a generalized form of compiler in that they take JavaScript text in and output text of some other language.Compilers try to convert the JavaScript text to a new set of text which has execution semantics for a different language-perhaps one with the special property that computers can directly execute it.You can think of them as a little man inside your computer flipping switches like 'print this character' based on instruction written in your JavaScript program. Interpreters actually perform the execution semantics by operating some machine-usually your computer.all take text in and attempt to do something with this conventional understanding of how to execute the code. Classes of programs called interpreters, compilers, transpilers, linters, highlighters, etc. JavaScript is a computer language, which is to say, narrowly, a set of conventions which allow us to read and interpret a bunch of text as having execution semantics-a fancy word for 'way of interpreting the language as a set of instructions'. This all gets dicey, and I often see really poor uses of language, so I'll be explicit and start from the bottom In common parlance, I think it's a bit atypical to call Node.js a framework, sure, but I'd have a hard time arguing as to why exactly it is not. It's a bit tough to say because these words are not well-defined.
