Another let issue

[mnowik]

I have an issue using let.

Here is my code:

if (a === b ) {
  let defaultReturnAddress = {};
  let returnAddress = _this.get('currentUser.address');
  ...
}
if (defaultReturnAddress) {...}

Here is the translation using ember-cli-babel@5.1.5

if (a === b ) {
  var _defaultReturnAddress = {};
  var returnAddress = _this.get('currentUser.address');
  ...
}
if (defaultReturnAddress) {...}

It seems to be linked to this error on babel #166.
This error was closed a while ago. However, it seems to be a Babel issue.

What's the issue here? let is block scoped, it seems to be having correctly. What output are you expecting?

[mnowik]

The if block is a scope by itself ?
I would have except var defaultReturnAddress

[sebmck]

let is called a block scoped variable so yeah let is bound to it. Closing as this isn't an issue and is expected behaviour.
