2. Because block scope doesn't exist pre-ES2015.

There's one more scope gotchas. It's around try-catch block. :)

How do you run JS in ES2015 environment? Clearly, Chrome's Console is the older environment since this code doesn't produce error:
{
function hello() {
return 'Hello!';
}
}
hello();

I run my snippets in NodeJS v13.

greet function in the last question actually runs without throwing a ReferenceError, tested here https://replit.com/@basantsoni/SillyGhostwhiteScreencast#index.js

it should be scoped to the enclosing scope(global in this case)
