486 PointsI am currently a little confused on the concepts of adding <scripts> to JavaScript. Also, what are they overall?
I'm new to programming and have a real desire to learn all I can. I'm currently working with Javascript and have been learning about <scripts>. I have been stuck on the "homework" problem stating that I need to, "add opening and closing script to the body." If I could get some assistance and how to do this and what <scripts> are in more depth that would be great. Thank you for your time.

You need to add opening and closing <script> tags in order to use JavaScript in your HTML document. I believe the best practice is to include your <script> tags right before the closing </body> tag. This way, the HTML and CSS have a chance to load before the JavaScript runs.
Between the <script> tags, you can include either JavaScript code, or a link to an external JavaScript file through the source attribute. The following code snippet provides an example of linking to the external JavaScript file:
<body> //opening body tag
<h1>Some WebPage</h1>
<script src="app.js"></script> </body> //closing body tag
In this example, you add the URL of the external script file in quotes after the "src" attribute and an "=" sign. You could place this same link between the HTML document's <head> tags, but you should probably avoid that practice. You can also write your JavaScript code directly inside of your HTML document between the <script> tags. The following code snippet provides an example of this:
<body>
<h1>Some WebPage</h1>
<script> alert("Warning!"); </script> </body>
When run, this code should result in an alert box displaying on your webpage with the text "Warning!". This same functionality can be accomplished by moving the code between the <script> tags in this example to a separate document. You could call this document "app.js", or whatever you want really, as long as you include the ".js" extension at the end of the filename. You can then access the code in that file by including the URL in the source attribute on the opening <script> tag, as demonstrated in the example above.
I hope that helps. Best of luck!

486 PointsThank you for your help! That sounds like a great idea to learn HTML. I'll go ahead and do that so I can jump back into JavaScript with a firmer foundation. I really appreciate the advice given!
