I have no knowledge of what allows QuickJS to run the tests faster, or if it even does run the tests faster, but QuickJS does have one big speed advantage over V8 in some circumstances: QuickJS allows ahead-of-time compilation of JS to byte code. This removes the need to parse the JS at execution time. It’s a pretty nifty feature.

Once upon a time, Firefox used to do that for extensions.

FWIW v8 does too through its "snapshot" feature. It's used by Chrome and Node.js to speed up the initialization of the standard library. It might even be faster because it includes both the bytecode and the heap.
