Prevent void 0 and replace them

[guiled]

(See this playground link)

Hi, I need to prevent void 0 operator in my result code, but I don't know how to do it.

I'm making a JS plugin (because this is a temporary plugin, may be used by JS dev only, moreover I still don't know Rust, and didn't manage to make one simple plugin work :-( ).

Input

const {b=42} = args

Output

var _b = args.b, b = _b === void 0 ? 42 : _b;

What I would like to do

var b = args.hasOwnProperty("b") ? args.b : 42;

Is there any way to do this ?

Thank you !
