Javascript is dynamically typed, and has 'const' variable declaration which
were added in ES6.

Static typing is not the only use case. Discouraging reuse of variables of
favouring functional style over imperative is a strong use case for 'const'
in JS.

But I agree that the scoping rules are different in Javascript, and this
argument is much less convincing in Python.
