No, the question asked was whether binaries output by scriptc, such as the tsc-ts compiler binary, include a garbage collector that runs while they're running. (The question was not about the output of tsc-ts.) If not, then that would raise a bunch of questions about how the TypeScript code that was fed into scriptc is being executed without a GC. It is true that a TypeScript compiler could be written in a non-GC language like Rust, but tsc-ts in particular is written in TypeScript, which needs a GC.
The answer, according to https://scriptc.dev/docs/limitations#weak-collections-and-me..., is that scriptc relies primarily on reference counting, augmented with a cycle collector that runs at specific times, kind of like Python.
