 ## Description
 <section id='description'>
 Sometimes you may need to iterate through all the keys within an object. This requires a specific syntax in JavaScript called a <dfn>for...in</dfn> statement. For our <code>users</code> object, this could look like:
-<blockquote>for (let user in users) {<br>&nbsp;&nbsp;console.log(user);<br>};<br><br>// logs:<br>Alan<br>Jeff<br>Sarah<br>Ryan</blockquote>
+<blockquote>for (let user in users) {<br>&nbsp;&nbsp;console.log(user);<br>}<br><br>// logs:<br>Alan<br>Jeff<br>Sarah<br>Ryan</blockquote>
 In this statement, we defined a variable <code>user</code>, and as you can see, this variable was reset during each iteration to each of the object's keys as the statement looped through the object, resulting in each user's name being printed to the console.
 <strong>NOTE:</strong><br>Objects do not maintain an ordering to stored keys like arrays do; thus a keys position on an object, or the relative order in which it appears, is irrelevant when referencing or accessing that key.

 Both Chrome and Firefox have excellent JavaScript consoles, also known as DevTools, for debugging your JavaScript.
-You can find Developer tools in your Chrome's menu or Web Console in FireFox's menu. If you're using a different browser, or a mobile phone, we strongly recommend switching to desktop Firefox or Chrome.

 The <code>console.log()</code> method, which "prints" the output of what's within its parentheses to the console, will likely be the most helpful debugging tool. Placing it at strategic points in your code can show you the intermediate values of variables. It's good practice to have an idea of what the output should be before looking at what it is. Having check points to see the status of your calculations throughout your code will help narrow down where the problem is.
 Here's an example to print 'Hello world!' to the console:
 <code>console.log('Hello world!');</code>
