+
+Comments are lines of code that JavaScript will intentionally ignore. Comments are a great way to leave notes to yourself and to other people who will later need to figure out what that code does.
+
+There are two ways to write comments in JavaScript:
+
+Using `//` will tell JavaScript to ignore the remainder of the text on the current line. This is an in-line comment:
+
+```js
+// This is an in-line comment.
+```
+
+You can make a multi-line comment beginning with `/*` and ending with `*/`. This is a multi-line comment:
+
+```js
+/* This is a
+multi-line comment */
+```
+
+**NOTE:** As you write code, you should regularly add comments to clarify the function of parts of your code. Good commenting can help communicate the intent of your code—both for others *and* for your future self.
+
+# --instructions--
+
+Try creating one of each type of comment.
+
+# --hints--
+
+You should create a `//` style comment that contains at least five letters.
+
+```js
+assert(code.match(/(\/\/)...../g));
+```
+
+You should create a `/* */` style comment that contains at least five letters.
+
+```js
+assert(code.match(/(\/\*)([^\/]{5,})(?=\*\/)/gm));
+```
+
+# --seed--

+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+// Fake Comment
+/* Another Comment */
+```
