-### ES2015+
-
-By default `eslint-config-problems` forces the use of ES2015+ features supported by Node.js versions 10 and higher. Here are the rules enforced:
-
-- `no-var` - Use `let`/`const` instead.
-- `object-shorthand` - Use object shorthand where possible.
-- `prefer-arrow-callback` - Use arrow functions as callbacks where possible.
-- `prefer-numeric-literals` - Don't use `parseInt()` to write binary, octal, and hexadecimal numbers, use the literal form instead.
-- `prefer-template` - Use template strings instead of string concatenation.
-- `prefer-spread` - Use the spread operator instead of `.apply` where possible.
-- `prefer-rest-params` - Use rest parameters instead of `arguments`.
-- Use the exponentiation operator (`**`) instead of `Math.pow()` (enforced via `no-restricted-properties`).
-- `prefer-object-spread` - Use object spread where possible, instead of `Object.assign()`
-- Use optional catch bindings when not using the error variable in the catch block (enforced by `no-unused-vars` with `caughtErrors: 'all'`)
-- `prefer-const` - I realize this is very opinionated; if you don't like it, add `prefer-const: off` to your config.
