HTML/CSS/JavaScript Overview

• HTML: Creates content (buttons, text, images).
• CSS: Styles appearance (design, layout).
• JavaScript: Adds interactivity (e.g., actions on button clicks).

Introduction to JavaScript

• JavaScript is a language to instruct computers to execute tasks.
• Used to create dynamic content on websites, e.g., form submissions, animations.
• Executable in web browsers like Google Chrome.

Basic JavaScript Syntax

• Commands are called code, executing code is "running" it.
• JavaScript syntax must be precise (case-sensitive).
• Simple commands: alert('Hello');, 2 + 2;

JavaScript Execution Environment

• Use browser console to test and run JavaScript code.
• Access via right-click > Inspect > Console in Chrome.

JavaScript Math Operations

• Can perform basic math: addition, subtraction, multiplication, division.
• Order of Operations: Follows mathematical precedence (PEMDAS).
• Syntax Rules: Use brackets () to define operation order.
• Special Operators: +, -, *, /.*

Working with Numbers

• Integers: Whole numbers.
• Floating Points: Decimal numbers (note potential precision issues).
• Rounding: Use Math.round() to round numbers.

Practical Examples

• Use JavaScript to calculate totals, costs, etc., on a webpage.
• Ensures accuracy in financial calculations (e.g., conversion to cents).

Handling Strings in JavaScript

• Strings: Text data enclosed in quotes.
• Concatenation: Combine strings using +.
• Escape Characters: Special characters like \n for new line.
• String Interpolation: Use backticks and ${} to insert variables.

HTML/CSS/JavaScript Integration

• Load JavaScript in HTML using <script> tags.
• Use event attributes like onclick to trigger JavaScript actions.

JavaScript and Web Development Tools

• VS Code: Recommended code editor.
• Live Server Extension: For auto-refreshing the browser.
• Indentation/Formatting: Use 2 spaces for indentation in code.

Advanced Concepts and Techniques

• Variables: Store data using let, const, and var.
• Booleans and Conditions: Use true/false and if statements for logic.
• Functions: Encapsulate reusable code blocks.
• Objects: Group related data and functions.

Project Development

• Rock Paper Scissors Game: Practice using IF statements and functions.
• To-Do List: Learn arrays and loops to manage dynamic data.

Key JavaScript Features

• DOM Manipulation: Access and modify webpage elements.
• Event Handling: Attach events to elements for interactive behavior.
• Modules: Organize code into reusable components, avoid naming conflicts.
