+      Sometimes it's nice to leave a clarifying note to future readers of the code (this could very well be you!) in plain English. This is called a comment, and it is only intended for humans to read, the computer knows to ignore them.
+      Here's what comments look like in JavaScript:
+
+    ```js
+    // this is a one line comment, here we're creating an array
+      var drawableObjects = [drawableSnake];
+    /*
+      this is a multi line comment
+      here we're drawing the snake
+    */
+    CHUNK.draw(drawableObjects);

+  ### Switch statement
+
+  A `switch` statement is another way to organize a seried of `if` and `else if`s. Here's an example:
+
+  ```js
+  switch(color) {
+    case "red":
+      return { action: "stop" };
+    case "orange":
+      return { action: "wait" };
+    case "green":
+      return { action: "go" };
+    default:
+      return { action: "unknown" };
+  }
+  ```
+
+  Can you figure out how to replace our snake game code above with a `switch` statement? (Don't worry, you'll see how we do it in the next lesson)
