Chaining variable assignments Example

There is an issue with the example mentioned in the following section

13.5 Don’t chain variable assignments.

Accessing the value of a would throw an Uncaught ReferenceError: a is not defined.

https://github.com/airbnb/javascript#variables–no-chain-assignment

// bad
(function example() {
  // JavaScript interprets this as
  // let a = ( b = ( c = 1 ) );
  // The let keyword only applies to variable a; variables b and c become
  // global variables.
  let a = b = c = 1;
}());

console.log(a); // undefined
console.log(b); // 1
console.log(c); // 1

``` `

Gotcha.

If you’re interested in making a PR, let’s just change the undefined comment to “throws ReferenceError” in all 4 places 😃 that seems easiest. Thoughts?

Fair point. I suppose we could add a let a; above the IIFE.

I think the purpose of the example is clear regardless, but that’s certainly a good tweak.
