Strangely formatted output

[stuffaboutpete]

Can anyone explain this output?

const { VM } = require('vm2');
console.log(new VM().run('[1, 2, 3]'));

[ 1, 2, 3, '0': 1, '1': 2, '2': 3 ]

The equivalent eval looks like this (as you'd expect)...

console.log(eval('[1, 2, 3]'));

[ 1, 2, 3 ]

Thanks @patriksimek, I'm still interested in an answer if someone has any insight.

@stuffaboutpete check #198 out.
One of workarounds is to downgrade Node to v8.10.0

Thank you @OleksiyRudenko. I'll close as these are definitely duplicates.

Plus, that workaround is useful for me 👍
