Explain Javasript language Describe client-side and server-side Javascript Describe build-in function Objectives

Javascript is a language that allows you build dynamic and interactive Web pages . Javascript is a scripting language developed by Sun Microsystems and Netscape. Javascript developed from Netscape’s Livescript Client application run in a broswer such as Netscape Navigator or Internet Explorer and Firefox Introduction

Sripting Scripting refers to a series of commands that are interpreted and executed sequentially and immediately on an occurrence of an event

Sripting Client side Scripting: Refer to a script being executed on the client’s machine by the browser. Server side Scripting: Refer to a script being executed on Web server to generate dynamic HTML pages .

<SCRIPT> Tag The <SCRIPT> tag defines a script for an HTML page to make them interactive There are two main purpose of the <SCRIPT> tag, which are: Identifies a given segment of script in the HTML page. Load an external script file .

Declaring Variable In Javascript, the var keyword is used to create a variable by allocating memory to it.

Rules Javascript is a case-sensitive language. These rules are that a variable name: Can consist of digit, underscore, and alphabets. Must begin with a letter or underscore character Cannot begin with a number and cannot contain any punctuation marks. Cannot contain any kind of special characters such as +,*,%,and so on. Cannot contain spaces Cannot be a Javascript keyword

Composite Data Types A composite data type stores a collection of multiple related values, unlike primitive data types.

“ null “ Keyword The null keyword specifies that a variable does not hold any value. (the null value is not equal to zero because zero is a calculate value while null refers to the absence of a value)

Methods to display Javascript allows you to display information using the methods of the document object . The document object is a predefined object in Javascript write () : display any type of data writeln(): Display any type of data and appends a new line character.

Comments JavaScript support two types of comments. There are: Single - line comments Multi - line comments

Esccap Sequences Character There are multiple escape sequence characters in Javascript that provides various kind of formatting.

JavaScript Keywords Keywords are predefined terms that can not be used as an object name, function name or variable name JavaScript Keyword break case comment continue default delete do else export for function if import in Label new return switch this typeof var void while with

Build-in Functions Function Description Example toFixed Specifies the number of digits to be displayed after the decimal point var price = 23.456; var fixedprice = price.toFixed(2) return 23.46 toPrecision Specifies the number of digits to be displayed from a given number var price = 45.9431 alert(price. toPrecision(3)) return 45.9 toString Convert any value into a string value var age=25; alert(‘Age:’ + age.toString()+’years’) Return Age: 25 years

Summary The Javascript runtime engine reads and executes the Javascript code either on the server or in the browser. The Server element includes JavaScript code, which is executed by the Web Server. The NOSCRIPT element specifies the alternate content to be displayed, if the browser closes not support Javascript.

Summary… Javascript provides various keywords: break, if, continue, new, this… The toFixed() function that specifies the number of digits to be displayed after the decimal point. The toPrecision() function specifies the number of digits in a number to be displayed to the user. The toString() function transforms a value into string. Building Dynamic Websites/Session 1/ of 16

JavaScript is the programming language of the web that allows for dynamic and interactive effects on web pages. It was created in the 1990s by Netscape and Sun Microsystems and has evolved through several versions. JavaScript code runs directly in the browser and is used to add interactivity to HTML pages through elements like variables, arrays, and functions. Common applications of JavaScript include slideshows, dropdown menus, form validation, popups, and automatic page refreshes. Its advantages include client-side execution, ease of use, and speed, while developers must be careful of issues like case sensitivity and proper syntax.

Java script basicsThakur Amit Tomer

JavaScript allows dynamic programming capabilities to be added to web pages. It is a lightweight scripting language executed in web browsers that is case sensitive. JavaScript code can be embedded directly in HTML pages between <script> tags or placed in external .js files. Code in the HTML body will execute as the page loads while code in the header is executed when called by functions in the body. Common events that can trigger JavaScript code include onload, onsubmit, onmouseover and onchange.

LSNIF: Locally-Subdivided Neural Intersection FunctionTakahiro Harada

Neural representations have shown the potential to accelerate ray casting in a conventional ray-tracing-based rendering pipeline. We introduce a novel approach called Locally-Subdivided Neural Intersection Function (LSNIF) that replaces bottom-level BVHs used as traditional geometric representations with a neural network. Our method introduces a sparse hash grid encoding scheme incorporating geometry voxelization, a scene-agnostic training data collection, and a tailored loss function. It enables the network to output not only visibility but also hit-point information and material indices. LSNIF can be trained offline for a single object, allowing us to use LSNIF as a replacement for its corresponding BVH. With these designs, the network can handle hit-point queries from any arbitrary viewpoint, supporting all types of rays in the rendering pipeline. We demonstrate that LSNIF can render a variety of scenes, including real-world scenes designed for other path tracers, while achieving a memory footprint reduction of up to 106.2x compared to a compressed BVH. https://arxiv.org/abs/2504.21627

Co-Constructing Explanations for AI Systems using ProvenancePaul Groth

Explanation is not a one off - it's a process where people and systems work together to gain understanding. This idea of co-constructing explanations or explanation by exploration is powerful way to frame the problem of explanation. In this talk, I discuss our first experiments with this approach for explaining complex AI systems by using provenance. Importantly, I discuss the difficulty of evaluation and discuss some of our first approaches to evaluating these systems at scale. Finally, I touch on the importance of explanation to the comprehensive evaluation of AI systems.
