Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

              <p id="lesson1">This will be replaced.</p>

<p id="math">Also replaced.</p>

<p>What happens to the value above when you uncomment line 7?</p>

<p> Now uncomment only line 9 and line 10. Note the change.</p>

<p>If you wanted to transform the sum into USA currency, you would need to quickly jump into more complex javascript as shown on the next line:</p>

<pre><code>sum = '$' + sum.toFixed(2).replace(/(\d)(?=(\d\d\d)+(?!\d))/g, "$1,");</pre></code>

<cite>http://stackoverflow.com/questions/14467433/currency-formatting-in-javascript</cite>

<p>Try copying the line of code onto line six in the JS window.<br> (Then make sure you comment out just lines 7, 9, and 10. You should see $64.00 in the maroon text above.)</p>

🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
