Typescript4j cannot compile the standard example

[dustpuppyNGTI]

On the example page (https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes.html) for typescript there is some simple code. This code cannot be compiled by typescript4j.

public class TypeScriptTest {
    private static final String code =
        "function greeter(person) {\n" +
        "    return \"Hello, \" + person;\n" +
        "}\n" +
        "var user = \"Jane User\";\n" +
        "document.body.innerHTML = greeter(user);\n";

    public static void main(final String... args) {
        final TypescriptCompiler typescript = new TypescriptCompiler();
        typescript.setEcmaScriptVersion(EcmaScriptVersion.ES5);
        typescript.compile(code);
    }
}

This results in the following error:

It seems that this is unmaintained, I wish that it was still, but sadly not.
