I was getting error: jsc.target should be es5 or upper to use getter / setter
and after investigation I've isolated issue and here is the "fix"

Linking to #1510 since we may need to apply the same concept to target options. We may also want to add some >= logic so that unrecognized target values translate to the newest swc target we know about.

Thanks for investigating and sending a fix. I want to throw together a regression test. What did you do to cause the error? And did it terminate the node process with a non-zero exit code, or did it log a warning? This info will help write a quick test.

in my tsconfig.json I have:

{
  "compilerOptions": {
    "target": "ES2021",
    ...
 },
  "ts-node": {
    "require": ["tsconfig-paths/register"],
    "files": true,
    "transpileOnly": true,
    "transpiler": "ts-node/transpilers/swc-experimental"
  }
}

then I was requiring a module from local module (I have monorepos setup).
in package.json of the module that I required there is:

{
  ...
  "files": [
    "build"
  ],
  ....
}

so that when this module is required build js and d.ts files are used.

as target for my tsconfig was es2021 in compiled js the use of property get syntax was not de-suggered.
I had something like

class Foo {
  get foo() {
    return "foo"
  }
}

and the error is here:

$ npm run foo

> foo
> ts-node --project ../../tsconfig.json ./src/foo.ts

I'm sure we would get same issue with ES2022.

Thanks for including all the details. At a glance, I could not find a list of every single target for swc. I thought it was in the swc documentation, but today I can't find it. Do you know where it is listed?

Does this look like a complete list?
