Introduction to JavaScript Lecture 6 CGS 3066 Fall 2016 October 6, 2016 JavaScript I Dynamic programming language. Program the behavior of web pages. I Client-side scripts to interact with the user. I Communicates asynchronously and alters document content. I Used with Node.js in server side scripting, game development, mobile applications, etc. I Has thousands of libraries that can be used to carry out various tasks. JavaScript is NOT Java I Names can be deceiving. I Java is a full-fledged object-oriented programming language. I Java is popular for developing large-scale distributed enterprise applications and web applications. I JavaScript is a browser-based scripting language developed by Netscape and implemented in all major browsers. I JavaScript is executed by the browsers on the client side. JavaScript and other languages JavaScript borrows the elements from a variety of languages. I Object orientation from Java. I Syntax from C. I Semantics from Self and Scheme. Whats a script? I A program written for a special runtime environment. I Interpreted (as opposed to compiled). I Used to automate tasks. I Operates at very high levels of abstraction. Whats JavaScript? I Developed at Netscape to perform client side validation. I Adopted by Microsoft in IE 3.0 (1996). I Standardized in 1996. Current standard is ECMAScript 6 (2016). I Specifications for ECMAScript 2016 are out. I CommonJS used for development outside the browser. JavaScript uses I JavaScript has an insanely large API and library.

Q. What Is Java ? Java Is a Programming Language and A
GANDHI CHOWK Q. What is Java ? Java is a programming language and a platform. Java is a high level, robust, secured and object-oriented programming language. Platform: Any hardware or software environment in which a program runs, is known as a platform. Since Java has its own runtime environment (JRE) and API, it is called platform. Where it is used? According to Sun, 3 billion devices run java. There are many devices where java is currently used. Some of them are as follows: 1. Desktop Applications such as acrobat reader, media player, antivirus etc. 2. Web Applications such as irctc.co.in, javatpoint.com etc. 3. Enterprise Applications such as banking applications. 4. Mobile 5. Embedded System 6. Smart Card 7. Robotics 8. Games etc. TYPES OF JAVA APPLICATIONS There are mainly 4 type of applications that can be created using java programming: 1) Standalone Application It is also known as desktop application or window-based application. An application that we need to install on every machine such as media player, antivirus etc. AWT and Swing are used in java for creating standalone applications. 2) Web Application An application that runs on the server side and creates dynamic page, is called web application. Currently, servlet, jsp, struts, jsf etc. technologies are used for creating web applications in java. Ishwar Prakash(8271395373) 1 GANDHI CHOWK 3) Enterprise Application An application that is distributed in nature, such as banking applications etc. It has the advantage of high level security, load balancing and clustering. In java, EJB is used for creating enterprise applications. -

Proposal to Refocus TC39-TG1 on the Maintenance of the Ecmascript, 3 Edition Specification
Proposal to Refocus TC39-TG1 On the Maintenance of the ECMAScript, 3rd Edition Specification Submitted by: Yahoo! Inc. Microsoft Corporation Douglas Crockford Pratap Lakshman & Allen Wirfs-Brock Preface We believe that the specification currently under development by TC39-TG1 as ECMAScript 4 is such a radical departure from the current standard that it is essentially a new language. It is as different from ECMAScript 3rd Edition as C++ is from C. Such a drastic change is not appropriate for a revision of a widely used standardized language and cannot be justified in light of the current broad adoption of ECMAScript 3rd Edition for AJAX style web applications. We do not believe that consensus can be reach within TC39-TG1 based upon its current language design work. However, we do believe that an alternative way forward can be found and submit this proposal as a possible path to resolution. Proposal We propose that the work of TC39-TG1 be reconstituted as two (or possibly three) new TC39 work items as follows: Work item 1 – On going maintenance of ECMAScript, 3rd Edition. In light on the broad adoption of ECMAScript, 3rd Edition for web browser based applications it is clear that this language will remain an important part of the world-wide-web infrastructure for the foreseeable future. However, since the publication of the ECMAScript, 3rd Edition specification in 1999 there has been feature drift between implementations and cross-implementation compatibility issues arising from deficiencies and ambiguities in the specification. The purpose of this work item is to create a maintenance revision of the specification (a 4th Edition) that focuses on these goals: Improve implementation conformance by rewriting the specification to improve its rigor and clarity, and by correcting known points of ambiguity or under specification. -

Supporting C Extensions for Dynamic Languages an Abbreviated Version of [10]
High-Performance Language Composition: Supporting C Extensions for Dynamic Languages An abbreviated version of [10]. Grimmer Matthias1, Chris Seaton2, Thomas W¨urthinger2 and Hanspeter M¨ossenb¨ock1 1 Johannes Kepler University, Linz, Austria fgrimmer,[email protected] 2 Oracle Labs fchris.seaton,[email protected] Abstract. Many dynamic languages such as Ruby offer functionality for writing parts of applications in a lower-level language such as C. These C extension modules are usually written against the API of an interpreter, which provides access to the higher-level language's internal data struc- tures. Alternative implementations of the high-level languages often do not support such C extensions because implementing the same API as in the original implementations is complicated and limits performance. In this paper we describe a novel approach for modular composition of languages that allows dynamic languages to support C extensions through interpretation. We propose a flexible and reusable cross-language mechanism that allows composing multiple language interpreters. This mechanism allows us to efficiently exchange runtime data across different interpreters and also enables the dynamic compiler of the host VM to inline and optimize programs across multiple language boundaries. We evaluate our approach by composing a Ruby interpreter with a C interpreter. We run existing Ruby C extensions and show how our system executes combined Ruby and C modules on average over 3× faster than the conventional implementation of Ruby with native C extensions. 1 Introduction Most programming languages offer functionality for calling routines in modules that are written in another language. There are multiple reasons why program- mers want to do this, including to run modules already written in another lan- guage, to achieve higher performance than is normally possible in the primary language, or generally to allow different parts of the system to be written in the most appropriate language.
