+# --description--
+
+In this lab you will create a function that converts a string to title case. Title case means that the first letter of each word is capitalized and the rest of the word is in lower case.
+
+`"Web Development Is Awesome"` is an example of a title cased string.
+
+**Objective**: Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should have a `titleCase` function that takes a string as an argument.
+1. The `titleCase` function should return a string with the first letter of each word capitalized and the rest of the word in lower case.
+1. `titleCase("I like to code")` should return `"I Like To Code"`.
+1. `titleCase("javaScript is fun")` should return `"Javascript Is Fun"`.
+
+# --hints--
+
+You should create a function named `titleCase`.
+
+```js
+assert.isFunction(titleCase);
+```
+
+`titleCase` should take a single argument.
+
+```js
+assert.lengthOf(titleCase, 1);
+```
+
+
+`titleCase("I'm a little tea pot")` should return a string.
+
+```js
+assert.isString(titleCase("I'm a little tea pot"));
+```
+
+`titleCase("I'm a little tea pot")` should return the string `I'm A Little Tea Pot`.
+
+```js
+assert.strictEqual(titleCase("I'm a little tea pot"), "I'm A Little Tea Pot");
+```
+
+`titleCase("sHoRt AnD sToUt")` should return the string `Short And Stout`.
+
+```js
+assert.strictEqual(titleCase('sHoRt AnD sToUt'), 'Short And Stout');
+```
+
+`titleCase("HERE IS MY HANDLE HERE IS MY SPOUT")` should return the string `Here Is My Handle Here Is My Spout`.
+
+```js
+assert.strictEqual(
+  titleCase('HERE IS MY HANDLE HERE IS MY SPOUT'),
+  'Here Is My Handle Here Is My Spout'
+);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+function titleCase(str) {
+  return str
+    .split(' ')
+    .map(word => word.charAt(0).toUpperCase() + word.substring(1).toLowerCase())
+    .join(' ');
+}
+```
