  +to the following:
  - Use `for ... of` whenever possible
  **Rationale:** `for ... of` is awesome. It's more readable than any other variant.
  -- Don't use `any` as much as possible
  +- Do not use `any` except when necessary
  - **Rationale:** The language is called *Type*Script, not *Untyped*Script. :wink: Static typing is wonderful. It catches bugs and improves readability. We should strive to use it as much as possible.

  - Use `const` wherever possible.
  - **Rationale:** Instead of reading `const` as "constant value," read it as "single assignment." Yes, it means "constant value" in other programming languages, but it's a little different in JavaScript.
  -
  -- When we can't use `const`, use `let`; never `var`
  -
  - **Rationale:** `var` trips up programmers in a number of cases - hoisting and closure capture are two big ones. Consider the difference between
  -
  - ```
  - for (var j = 0; j < 5; j++) { setTimeout(() => console.log(j), 5) }
  - ```
  -
  - and
  -
  - ```
  - for (let j = 0; j < 5; j++) { setTimeout(() => console.log(j), 5) }
  - ```
  -
  - Even if you're not capturing the variable, who knows if someone else might later?
