+# --description--
+
+This lab is about converting special characters in a string with their corresponding HTML entities.
+
+**Objective**: Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should have a `convertHTML` function that accepts a string as an argument.
+1. The `convertHTML` function should return a new string by converting special characters in the argument string to their corresponding HTML entities.
+
+   - `&` should be converted to `&`.
+   - `<` should be converted to `&lt;`.
+   - `>` should be converted to `&gt;`.
+   - `"` should be converted to `&quot;`.
+   - `'` should be converted to `&apos;`.
+
+# --hints--
+
+You should have a `convertHTML` function.
+
+```js
+assert.isFunction(convertHTML);
+```
+
+`convertHTML("Dolce & Gabbana")` should return the string `Dolce &amp; Gabbana`.
+
+```js
+assert.match(convertHTML('Dolce & Gabbana'), /Dolce &amp; Gabbana/);
+```
+
+`convertHTML("Hamburgers < Pizza < Tacos")` should return the string `Hamburgers &lt; Pizza &lt; Tacos`.
+
+```js
+assert.match(
+  convertHTML('Hamburgers < Pizza < Tacos'),
+  /Hamburgers &lt; Pizza &lt; Tacos/
+);
+```
+
+`convertHTML("Sixty > twelve")` should return the string `Sixty &gt; twelve`.
+
+```js
+assert.match(convertHTML('Sixty > twelve'), /Sixty &gt; twelve/);
+```
+
+`convertHTML('Stuff in "quotation marks"')` should return the string `Stuff in &quot;quotation marks&quot;`.
+
+```js
+assert.match(
+  convertHTML('Stuff in "quotation marks"'),
+  /Stuff in &quot;quotation marks&quot;/
+);
+```
+
+`convertHTML("Schindler's List")` should return the string `Schindler&apos;s List`.
+
+```js
+assert.match(convertHTML("Schindler's List"), /Schindler&apos;s List/);
+```
+
+`convertHTML("<>")` should return the string `&lt;&gt;`.
+
+```js
+assert.match(convertHTML('<>'), /&lt;&gt;/);
+```
+
+`convertHTML("abc")` should return the string `abc`.
+
+```js
+assert.strictEqual(convertHTML('abc'), 'abc');
+```
+
+# --seed--
+
+## --seed-contents--
+
+```js
+
+```
+
+# --solutions--
+
+```js
+const map = {
+  '&': '&amp;',
+  '<': '&lt;',
+  '>': '&gt;',
+  '"': '&quot;',
+  "'": '&apos;'
+};
+
+function convertHTML(str) {
+  return str.replace(/[&<>"']/g, function(char) {
+    return map[char];
+  });
+}
+```
