+Returns `true` if the string is `y`/`yes` or `false` if the string is `n`/`no`.
+
+Use `RegExp.test()` to check if the string evaluates to `y/yes` or `n/no`.
+Omit the second argument, `def` to set the default answer as `no`.
+
+```js
+const yesNo = (val, def = false) =>
+  /^(y|yes)$/i.test(val) ? true : /^(n|no)$/i.test(val) ? false : def;
