WHY JAVASCRIPT? • JavaScript is the language of the web browser — it is the most widely deployed programming language in history • At the same time, it is one of the most despised and misunderstood programming languages in the world • The amazing thing about JavaScript is that it is possible to get work done with it without knowing much about the language, or even knowing much about programming. It is a language with enormous expressive power. It is even better when you know what you’re doing — JAVASCRIPT: THE GOOD PARTS , DOUGLAS CROCKFORD WHY JAVASCRIPT? • Q: If you had to start over, what are the technologies, languages, paradigms and platforms I need to be up- to-date and mastering in my new world of 2014? • A: Learn one language you can build large systems with AND also learn JavaScript. • JavaScript is the language of the web. The web will persist and the web will win. That's why I suggest you learn JavaScript — S C O T T HANSELMAN , 2 0 1 4 WHAT IS JAVASCRIPT? • JavaScript is a cross-platform, object-oriented, functional, lightweight, small scripting language. • JavaScript contains a standard library of built-in objects, such as Array and Math, and a core set of language elements such as operators, control structures, and statements.

  • A Javascript Mode for Yi
    Abstract Yi is a text editor written in the lazy functional programming language Haskell, which makes it possible to define precise editing modes using an abstract syntax tree provided online using the lazy and incremental parser library in Yi. We have developed a JavaScript mode for this editor using this parser library to accurately point out possible errors in the source code. The mode accurately highlights syntactical errors as the user types and pro- vides a verifier to check the semantics of the source code. It supports most of the syntax from JavaScript 1.8 and can readily be extended with more functionality. The mode can also be used as a starting point for future developers of C-like modes for Yi. Writing a responsive parser for Yi proved non-trivial, because of the trade-off between parser performance and accuracy. This report describes how to write a mode for Yi and the different problems encountered during the working process of the JavaScript mode. It also describes in what ways the problems were solved. Sammanfattning Yi är en textredigerare skriven i det lata funktionella programspråket Haskell, som gör det möjligt att definiera noggranna redigeringslägen med hjälp av ett abstrakt syntaxträd som tillhandahålls av det lata och inkre- mentella parsningsbiblioteket i Yi. Vi har utvecklat ett JavaScript-läge till denna redigerare med hjälp av detta parsningsbibliotek för att exakt utpeka möjliga fel i källkoden. Läget markerar syntaktiska fel medan användaren skriver och tillhandahåller en verifierare för att kontrollera semantiken i källkoden. Det stödjer större delen av syntaxen i JavaScript 1.8 och kan enkelt utökas med mer funk- tionalitet.

  • Kaang: a Restful API Generator for the Modern Web
    Kaang: A RESTful API Generator for the Modern Web Ricardo Queirós CRACS & INESC-Porto LA & DI/ESMAD/P.PORTO, Porto, Portugal [email protected] https://orcid.org/0000-0002-1985-6285 Abstract Technology is constantly evolving, as a result, users have become more demanding and the ap- plications more complex. In the realm of Web development, JavaScript is growing in a surprising way, already leaving the boundaries of the browser, mainly due to the advent of Node.js. In fact, JavaScript is constantly being reinvented and, from the ES2015 version, began to include the OO concepts typically found in other programming languages. With Web access being mostly made by mobile devices, developers face now performance challenges and need to perform a plethora of tasks that weren’t necessary a decade ago, such as managing dependencies, bundling files, minifying code, optimizing images and others. Many of these tasks can be achieved by using the right tools for the job. However, developers not only have to know those tools, but they also must know how to access and operate them. This process can be tedious, confusing, time-consuming and error-prone. In this paper, we present Kaang, an automatic generator of RESTFul Web applications. The ultimate goal of Kaang is to minimize the impact of creating a RESTFul service by automating all its workflow (e.g., files structuring, boilerplate code generation, dependencies management, and task building). This kind of generators will benefit two types of users: will help novice developers to decrease their learning curve while facing the new frameworks and libraries commonly found in the modern Web and speed up the work of expert developers avoiding all the repetitive and bureaucratic work.

  • Javascript Overview
    JJAAVVAASSCCRRIIPPTT -- OOVVEERRVVIIEEWW http://www.tutorialspoint.com/javascript/javascript_overview.htm Copyright © tutorialspoint.com What is JavaScript ? Javascript is a dynamic computer programming language. It is lightweight and most commonly used as a part of web pages, whose implementations allow client-side script to interact with the user and make dynamic pages. It is an interpreted programming language with object-oriented capabilities. JavaScript was first known as LiveScript, but Netscape changed its name to JavaScript, possibly because of the excitement being generated by Java. JavaScript made its first appearance in Netscape 2.0 in 1995 with the name LiveScript. The general-purpose core of the language has been embedded in Netscape, Internet Explorer, and other web browsers. The ECMA-262 Specification defined a standard version of the core JavaScript language. JavaScript is a lightweight, interpreted programming language. Designed for creating network-centric applications. Complementary to and integrated with Java. Complementary to and integrated with HTML. Open and cross-platform Client-side JavaScript Client-side JavaScript is the most common form of the language. The script should be included in or referenced by an HTML document for the code to be interpreted by the browser. It means that a web page need not be a static HTML, but can include programs that interact with the user, control the browser, and dynamically create HTML content. The JavaScript client-side mechanism provides many advantages over traditional CGI server-side scripts. For example, you might use JavaScript to check if the user has entered a valid e-mail address in a form field. The JavaScript code is executed when the user submits the form, and only if all the entries are valid, they would be submitted to the Web Server.

  • {Download PDF} If Hemingway Wrote Javascript
    IF HEMINGWAY WROTE JAVASCRIPT PDF, EPUB, EBOOK Angus Croll | 192 pages | 21 Jan 2015 | No Starch Press,US | 9781593275853 | English | Daly City, California, United States If Hemingway Wrote JavaScript PDF Book While we might be able to write about cooking in English, we would be lacking in the vocabulary and paradigms present in French that are essential to cooking. Netscape 4 came with its own document. Yet Adobe has already released Premiere Express for online video editing and is putting the finishing touches on Photoshop Express for Web-based photo editing. They develop new software programs and write languages that computers can follow. Even though web pages from different domains can be displayed at the same time, either in separate browser windows or in separate frames within the same browser window, the JavaScript running on a web page belonging to one domain cannot access any information about a web page from a different domain. Initially, Netscape 2 was the only browser to support a scripting language and that language was originally called LiveScript. Currying is not implicit in JavaScript. Sure, in many ways it's technically possible to accomplish given that JavaScript is a powerful technology with the capability to manipulate images, carry out animation timing, etc. If you err on the side of viewing JavaScript as an "enhancement technology," you're unlikely to go wrong. JavaScript cannot close a window if it didn't open it. This is sounding more like the Web we know and love, a web of pages. We should have a diversity of programming languages.

  • How It Feels to Learn Javascript in 2016
    Jose Aguinaga Follow Web Engineer. Previously @numbrs, @plaidhq, currently @getflynt. Javascript, #people, startups, finte… Oct 3, 2016 · 12 min read How it feels to learn JavaScript in 2016 No JavaScript frameworks were created during the writing of this article. The following is inspired by the article “It’s the future” from Circle CI. You can read the original here. This piece is just an opinion, and like any JavaScript framework, it shouldn’t be taken too seriously. Hey, I got this new web project, but to be honest I haven’t coded much web in a few years and I’ve heard the landscape changed a bit. You are the most up-to date web dev around here right? -The actual term is Front End engineer, but yeah, I’m the right guy. I do web in 2016. Visualisations, music players, flying drones that play football, you name it. I just came back from JsConf and ReactConf, so I know the latest technologies to create web apps. Cool. I need to create a page that displays the latest activity from the users, so I just need to get the data from the REST endpoint and display it in some sort of filterable table, and update it if anything changes in the server. I was thinking maybe using jQuery to fetch and display the data? -Oh my god no, no one uses jQuery anymore. You should try learning React, it’s 2016. Oh, OK. What’s React? -It’s a super cool library made by some guys at Facebook, it really brings control and performance to your application, by allowing you to handle any view changes very easily.
