There are two main differences of `var` compared to `let/const`:

1. `var` variables have no block scope, their visibility is scoped to current function, or global, if declared outside function.
1. `var` variables have no block scope, their visibility is scoped to current function, or global, if declared outside any function.
2. `var` declarations are processed at function start (script start for globals).

There's one more very minor difference related to the global object, that we'll cover in the next chapter.

These differences make `var` worse than `let` most of the time. Block-level variables is such a great thing. That's why `let` was introduced in the standard long ago, and is now a major way (along with `const`) to declare a variable.
