+# --description--
+
+Previously you used the following code to declare a variable:
+
+```js
+var myName;
+```
+
+But you can also declare a string variable like this:
+
+```js
+var myName = "your name";
+```
+
+`"your name"` is called a <dfn>string</dfn> <dfn>literal</dfn>. A string literal, or string, is a series of zero or more characters enclosed in single or double quotes.
+
+# --instructions--
+
+Create two new string variables: `myFirstName` and `myLastName` and assign them the values of your first and last name, respectively.
+
+# --hints--
+
+`myFirstName` should be a string with at least one character in it.
+
+```js
+assert(
+  (function () {
+    if (
+      typeof myFirstName !== 'undefined' &&
+      typeof myFirstName === 'string' &&
+      myFirstName.length > 0
+    ) {
+      return true;
+    } else {
+      return false;
+    }
+  })()
+);
+```
+
+`myLastName` should be a string with at least one character in it.
+
+```js
+assert(
+  (function () {
+    if (
+      typeof myLastName !== 'undefined' &&
+      typeof myLastName === 'string' &&
+      myLastName.length > 0
+    ) {
+      return true;
+    } else {
+      return false;
+    }
+  })()
+);
+```
