Nope. A variable is only global if you are in non-strict mode and leave off a `var` on the declaration, or explicitly assign to the global scope (aka window in the browser).

Object internal state is generally true, if you're using prototypal objects. Use function closures when you need to internalize something.

Speaking of which, anything hidden via closure is truly hidden and can't be overridden. Anything public can be overridden, excepting objects frozen via the ES5 spec's Object.freeze method.

I generally enjoy most aspects of JS, and generally detest working with CSS, in large part because I delegate interacting with many browser APIs to JS libraries, whereas there's no escaping the awfulness that is years of backwards compatibility with incompatible vendor specs and CSS implementations.

I suspect I'll be happier once CSS Grids are universally supported (properly) among all of the browsers I need to target, and use postcss for the rest.
