var is worse than that

[erights]

https://github.com/airbnb/javascript#hoisting--about starts with

var declarations get hoisted to the top of their scope

and the following text suggests that this is the same notion of scope as the scope that let and const hoist to. Rephrase to something like "top of the block of their enclosing function"
