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.

Introduction to JavaScript
Introduction to JavaScriptMarlon Jamera This document provides an introduction to JavaScript, covering topics such as:
- The scope of the lesson includes an introduction to JavaScript, using JavaScript code, syntax, data types, objects, strings, functions, and standard popup boxes.
- JavaScript is a client-side scripting language that allows interactivity on web pages by modifying HTML content and handling events. It is interpreted by web browsers rather than compiled.
- JavaScript code can be embedded directly in HTML, or linked via external .js files, and is executed when the page loads or in response to events.

Introduction to Javascript By Satyen
Introduction to Javascript By SatyenSatyen Pandya This document provides an introduction to JavaScript, including:
- JavaScript is a scripting language used to programmatically access computational objects in a host environment and is prototype-based and dynamically typed.
- It was initially created by Netscape in 1995 under the name LiveScript and later renamed to JavaScript.
- JavaScript implementations have three main parts - the core ECMAScript language, the Document Object Model (DOM) for manipulating HTML/XML documents, and the Browser Object Model (BOM) for accessing browser capabilities.
- The DOM represents documents as nodes that can be traversed and manipulated, with levels that have added functionality over time. The BOM allows manipulating browser windows and accessing information about the browser, screen,

JavaScript Good Practices
JavaScript Good PracticesJussi Pohjolainen This document discusses various JavaScript best practices including:
- JavaScript is object-oriented with only 5 primitive types
- Objects are collections of key-value pairs where some values can be functions
- Variables should be declared with "var" to avoid global scope issues
- Function scoping and variable hoisting can cause confusion; variables should be declared at the top of functions
- Strict equality ("===") is safer than abstract equality ("==")
- Global variables should be avoided, and code quality tools like JSLint can help identify issues

Introduction To JavaScript Ajax
Introduction To JavaScript AjaxReema Ajax allows web pages to be updated asynchronously by exchanging data with a server in the background without reloading the entire page. It uses JavaScript and XMLHttpRequest objects to retrieve data from the server and update portions of the page without interfering with its display or behavior. The XMLHttpRequest object's open() and send() methods are used to send requests to the server and retrieve new data, which can then update parts of the web page asynchronously.
CSS Basic Introduction
CSS Basic IntroductionReema This document provides an introduction to CSS (Cascading Style Sheets) including CSS syntax, selectors, and tips. CSS is used to describe how HTML elements are displayed on different mediums and can control layout and styles across multiple web pages. CSS syntax uses selectors to target HTML elements for styling and declaration blocks to set property values. Selectors can be simple like element, id, or class selectors, or more complex like combinator, pseudo-class, pseudo-element, or attribute selectors. Common selectors include id selectors using #, class selectors using ., universal selectors using *, and grouping selectors.

The viewport meta tag allows controlling page dimensions and scaling. RWD uses a grid system divided into columns, box-sizing to include padding and borders, and media queries with CSS properties for certain screen widths. It follows a mobile-first approach where mobile styles are set as default and overridden by larger screens. Images and videos are made responsive using width:100% and max-width:100%.
How To Add CSS The Correct Way.
How To Add CSS The Correct Way.Reema There are three ways to add CSS to an HTML document: external, internal, and inline CSS. External CSS allows you to change the styling of an entire website by editing one CSS file linked via <link> tags. Internal CSS defines styles within <style> tags in the <head> for a single page. Inline CSS uses the style attribute on individual elements to uniquely style them.
CSS Basic Introduction, Rules, And Tips
CSS Basic Introduction, Rules, And TipsReema This document provides an introduction to CSS (Cascading Style Sheets) including CSS syntax, selectors, and tips. CSS is used to describe how HTML elements are displayed on different mediums and can control layout across multiple web pages. CSS syntax uses selectors to target HTML elements for styling. Selectors can be simple like element names, ids, or classes, or more complex like combinators, pseudo-classes, pseudo-elements, or attributes. Common selectors include id, class, universal, and grouping selectors.
HTML Semantic Elements
HTML Semantic ElementsReema Semantic HTML elements like <header>, <nav>, <article>, <section>, and <footer> help describe the meaning and purpose of content. Non-semantic elements like <div> do not provide semantic information. Common sections of a webpage such as navigation, content articles, and footers can now be marked up with the appropriate semantic elements to clearly define the structure and roles for both browsers and developers.
Introduction:
Introduction:Reema Front-end web development involves programming the user interface of a web application using HTML, CSS, and JavaScript rather than database or server-side programming. It includes everything from simple HTML pages to complex responsive websites designed to work across different browsers, devices, and screen sizes. Front-end development focuses on the Hypertext Markup Language (HTML), Cascading Style Sheets (CSS) and JavaScript portion of web site production.
