JavaScript allows for interactivity on web pages by manipulating HTML elements and reacting to user actions. It is a scripting language that runs in web browsers and is used to validate form input, detect browsers, and create dynamic content. JavaScript code is embedded within HTML pages and works together with HTML for content and CSS for presentation.
This document provides information about Java and JavaScript by comparing and contrasting the two programming languages. It discusses that Java is a compiled programming language that can be used to create both web browser applications and standalone applications, while JavaScript is an interpreted scripting language that runs within web browsers. The document also explains what JavaScript can do, such as manipulate HTML, react to user events, and validate form data. It provides examples of basic JavaScript code and how it can be used with HTML forms.
JavaScript is a scripting language that adds interactivity to HTML pages. It can dynamically manipulate HTML elements, validate user input, and respond to events like mouse clicks or page loads. JavaScript code can be embedded directly in HTML files or linked via external .js files and placed in the <head> or <body> sections. Common uses of JavaScript include displaying popup boxes, handling form validation, and dynamically updating content.
Java Script is one of the most pervasive languages found on the internet and World Wide Web. Java Script is useful in making web pages more interactive. The pages can be made to react to the actions of the users in the form of special effects, both visual and otherwise.
JavaScript is a scripting language used to create dynamic web page content and applications. It allows inserting scripts into HTML pages to interact with users and dynamically change elements on web pages. JavaScript is an interpreted, object-oriented programming language that is cross-platform and can be inserted into HTML pages using <script> tags. It is used to write scripts that validate form data, write dynamic text content, respond to user events, and read/write HTML elements.
JavaScript was designed to add interactivity to HTML pages. It is a scripting language that is usually embedded directly into HTML pages and allows programmers to put dynamic text and react to events. JavaScript can be used to validate data, detect the visitor's browser, create cookies, and read and write HTML elements. It uses semicolons, handles old browser versions, is case sensitive, and ignores whitespace. Variables can be local or global and datatypes include empty, null, boolean, char, integer, long, float, double, date, string, and object. JavaScript supports operators, conditional statements, looping statements, and functions.
The document introduces JavaScript programming and provides guidelines for adding JavaScript to web pages. It discusses using <script> tags to add internal or external JavaScript, and how to access the JavaScript console in browsers to debug errors. The chapter concludes with an assignment to add an alert box to a sample HTML file to write the first JavaScript program.
JavaScript is a programming language that conforms to the ECMAScript specification. It is high-level, often just-in-time compiled, and multi-paradigm with curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions. A JavaScript function is a block of code that can be executed when called, such as when a user clicks a button on a webpage. Scripts written in JavaScript can be placed in the head or body section of an HTML document or both.

</body> </body>
</html> </html>
5. The <SCRIPT> and </SCRIPT> tags are the main way of
connecting JavaScript code to HTML. You are free to
embed as many scripts into a single HTML document as
you like using multiple <SCRIPT> tags.
Script tags What it does
<script language= “JavaScript> Tells your browser that JavaScript
code is about to appear
alert(“Welcome….”); -Statements
(object, properties, function, vari
ables , methods, and events.
-Semi colon terminates the
statements
</script> Tells the browser that the
JavaScript code is all done and it
can go back to HTML code
6. DISPLAYING TEXT

7. SUMMARY
Writing/Scripting in JavaScript
JavaScript code is typically embedded in the
HTML, to be interpreted and run by the client's
browser. Here are some tips to remember when
writing JavaScript commands.
• JavaScript appears within the <Head> and <Body>
sections of an HTML document.
• JavaScript code is case sensitive
• White space between words and tabs are ignored
• Line breaks are ignored except within a statement
• JavaScript statements end with a semi- colon (;)
8. • A JavaScript code is a sequence of statements
that can be embedded into an HTML page and
executed directly by a Web browser to generate
dynamic HTML page.
• Scripting in JavaScript entails working with
objects, which you can create yourself or use
those built-in the language.
• You can access information(properties) about the
objects, perform actions(methods) on them and
responds(event handler) to the events that
happen to them.
• Objects, properties, methods, and event handlers
are the building blocks of JavaScript programs.
