Are variables declared in module scope not properties of the module object?

Question

In browsers global variables are actually properties of window object.

If I declare a variable with var keyword in Node.js then will it be a property of module object?

var aaa = 'aaa';
console.log(module.aaa); // undefined

Why is it undefined? Doesn't module object in Node.js follow the same logic as global object in browsers?

No, and that explains why it is undefined. Anything defined inside a module is enclosed in that module unless exposed explicitly via exports or module.exports.

So it will be like a "normal" local variable? Like local variables in functions that aren't properties of any object? Just to make sure I understand correctly
