+Generates all right substrings of a given string.
+
+- Use `String.prototype.length` to terminate early if the string is empty.
+- Use a `for...in` loop and `String.prototype.slice()` to `yield` each substring of the given string, starting at the end.
+
+```js
+const rightSubstrGenerator = function* (str) {
+  if (!str.length) return;
+  for (let i in str) yield str.slice(-i - 1);
+};
+```
+
+```js
+[...rightSubstrGenerator('hello')];
+// [ 'o', 'lo', 'llo', 'ello', 'hello' ]
+```
