A script is a small bit of code that enables web browsers to do something more than just displaying static results. Scripts are used in web design to create dynamic pages. So far you have included noscript inside your polymer element. The reason is because untill now we did not use the script functionalities. There are some big differences between regular HTML scripts and Polymer scripts. Scripts are extremely powerful and are responsible for the behaviour of your web-app.
Open the plunker file in the resources and press run
Add the script tag
Inside the script tag target the blockquote by using its ID
Change the background color of the element using a script
The font of the author is too small make it bigger using a script

Now you know how to use scripts in regular HTML but how do you do that in Polymer? When you do not include a script, you need to explicitly tell Polymer that by adding the noscript attribute. When you do, you leave that attribute out. In Polymer the syntax to include a script is different from that in regular HTML. Till now all the Polymer elements included this noscript. This time we add the basic syntax to include a script inside a Polymer component.
Open the plunker file
Look at the basic script set up syntax
Remove the no script to start using the script
You do not have to add a script try to understand the syntax needed to allow the script to work
The values that are set contain content try to find where that content is transferred to
Plunker: Set up a script in Polymer
In this case we will use the script to set our values, and we will use the double bracket method (like handlebars) to insert those values elsewhere. In Polymer we do not have to target specific elements. The element containing the script already indicates where we want our script to run. This is an example where we do not just alter the styling anymore but use a script to store information. This is useful in combination with the repeat attribute of Polymer's template tag.
Open the plunker file
Inside the script there are two objects styles and quotes
Inside the blockquote you will find the word category
Replace the word category with a word that appropriatly describes it like "humor" or "sad"
Replace it by adding a field in the quotes object and using the double brackets to display it where it says category
