This is parsing with the following options:
meriyah.parse(code, {
module: isModule,
impliedStrict: isModule,
ranges: true,
raw: true,
preserveParens: false,
globalReturn: true,
webcompat: true,
next: true,
});
acorn.Parser.parse(code, {
ecmaVersion: 'latest',
sourceType: isModule ? 'module' : 'script',
preserveParens: false,
allowHashBang: true,
allowReturnOutsideFunction: true,
});isModule depends on whether module appears in flags in the YAML header comment at top of each test case file.
