+## sub-configs

+### `node8`
 
 There is a sub-config, accessible at `problems/node8`, which forces ES features supported by Node.js 8+. Specifically, it enforces the use of the exponentiation operator instead of `Math.pow()`.
 
 It also sets `ecmaVersion: 2017` in the `parserOptions`, so that ESLint can parse `async`/`await` code with no additional setup.

-If you disagree; feel free to open an issue. I'm open to changing rules if you have a good reason.
+The `problems/node10` sub-config forces ES2018 features supported by Node.js v10+. Specifically, it disallows the use of `Object.assign()` where the object spread operator could be used.
