JavaScript is a scripting language that enhances functionality and appearance of web pages. It allows pages to be more dynamic and interactive through features like form validation, cookies, and animations. JavaScript code is embedded directly into HTML and runs in web browsers and other environments. A basic JavaScript program prints text to a web page. It uses <script> tags to indicate JavaScript code and document.writeln() to output text. User input can be obtained through prompts, which pop up dialog boxes. Variables are used to store and work with input data. The code examples demonstrate basic output and input methods in JavaScript.

What is the DOM?
The DOM is a W3C (World Wide Web Consortium) standard.
The DOM defines a standard for accessing documents:
"The W3C Document Object Model (DOM) is a platform and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a document."
The W3C DOM standard is separated into 3 different parts:
Core DOM - standard model for all document types
XML DOM - standard model for XML documents
HTML DOM - standard model for HTML documents
The HTML DOM (Document Object Model)
When a web page is loaded, the browser creates a Document Object Model of the page.
The HTML DOM model is constructed as a tree of Objects.
With the HTML DOM, JavaScript can access and change all the elements of an HTML document.

If you are using jQuery, you need to understand the Document Object Model and how it accounts for all the elements inside any HTML document or Web page.
JavaScript - An Introduction is a beginner's guide to JavaScript. It starts with very basic level and goes to intermediate level. You'll be introduced with every language constructs, Event handling, Form handling and AJAX which is supported by JavaScript with XMLHttpRequest object. This XHR object is discussed in enough detail so that you can understand how the underlying AJAX functionality works in jQuery. At the end it discusses advance concepts and library build on/around JavaScript.

This article is the first part of a series of articles on using JavaScript tools. Today, JavaScript is a very powerful language that can be used to build web apps, mobile apps, and even some pc games — perhaps a bit faster than you would build them otherwise.
New libraries have emerged in the web industry to address the challenges of JavaScript — libraries such as JQuery, Prototype and many others have been released. Today, a popular question asked by many is — should i learn the libraries such as jQuery or learn basic JavaScript. The truth is that the libraries help you to create faster, responsive JavaScript, but there are still times when your basic knowlege of JavaScript will be called into question. It is for this reason that I have created this eBook, to assist newbies learn JavaScript.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

3. Why JavaScript? Enhances functionality and appearance of the web page. Client-side scripting Makes pages more dynamic and interactive Easy-to-use Built into web browsers and other applications Offering functions such as Form validation (JS can be used to validate data before it is submitted to a server. This saves the server from extra processing). JavaScript can be used to set and retrieve web cookies (A JavaScript can be used to store and retrieve information on the visitor's computer). Cool stuff like drop-down menus. Hide and show elements. Animation. JS

23. JavaScript Data Types and Variables Variable is a facility for storing data. The current value of the variable is the data actually stored in the variable. Variable in JavaScript has name and value Declare a variable give it a name ( ex. var x ) Initialize a variable give it a value ( ex. x = 100) In order to use variable, they must be declared and initialized. Variable types are not important in JavaScript. They may be interchanged as necessary. This means that if a variable is a string one minute, it can be an integer the next. Declare initialize Call
