Generally speaking, a function is a "subprogram" that can be called by code external (or internal in the case of recursion) to the function. Like the program itself, a function is composed of a sequence of statements called the function body. Values can be passed to a function, and the function will return a value.
In JavaScript, functions are first-class objects, because they can have properties and methods just like any other object. What distinguishes them from other objects is that functions can be called. In brief, they are Function objects.
CSS (Cascading Style Sheets) is the code that styles web content. With CSS, you can control the color, font, the size of text, the spacing between elements, how elements are positioned and laid out, what background images or background colors are to be used, different displays for different devices and screen sizes, and much more!.

JavaScript is a scripting language that runs in web browsers. It allows for dynamic interactions and effects on web pages. JavaScript code can run on the client-side to process user input and update pages in real-time without reloading. It is commonly used with HTML and CSS to create interactive web applications. Some key points covered are that JavaScript is weakly typed, prototype-based, and runs directly in web browsers to enhance the user experience.
JavaScript was designed to add interactivity to HTML pages. It is a scripting language that is usually embedded directly into HTML pages and allows for dynamic text, event handling, reading/writing HTML elements, and validating form data. JavaScript supports both client-side and server-side scripting and was originally developed by Netscape under the name LiveScript before being renamed. It provides programming capabilities to HTML authors and allows for dynamic content, user interaction, and validation without server requests.

program-related requests
• Client-side programs can never replace server-
side programming
6New Perspectives on HTML5, CSS3, and JavaScript, 6th Edition
8. XPXPXPXPXPThe Development of JavaScript
• JavaScript is a programming language for
client-side programs
• It is an interpreted language that executes a
program code without using an application
• Compiler is an application that translates a
program code into machine language
• JavaScript code can be directly inserted into or
linked to an HTML file
8New Perspectives on HTML5, CSS3, and JavaScript, 6th Edition
9. XPXPXPXPXPWorking with the script Element
• JavaScript code is attached to an HTML file
using the script element
<script src=”url”></script>
where url is the URL of the external file
containing the JavaScript code
• An embedded script can be used instead of an
external file by omitting the src attribute
<script>
code
</script>
9New Perspectives on HTML5, CSS3, and JavaScript, 6th Edition
10. XPXPXPXPXPLoading the script Element
• script element can be placed anywhere
within an HTML document

immediately stops loading the page and begins
loading and then processing the script
commands
• async and defer attributes can be added to
script element to modify its sequence of
processing
10New Perspectives on HTML5, CSS3, and JavaScript, 6th Edition
11. XPXPXPXPXPLoading the script Element (continued)
