Async javascript. Overview js async js features, from callback to async function and async generators
Happy Programming with CoffeeScript
CoffeeScript is a programming language that compiles to JavaScript. It adds syntactic sugar like string interpolation and array comprehensions to make code more concise and readable in a JavaScript-like syntax. While CoffeeScript is not a replacement for JavaScript, it can help programmers write cleaner code, especially for those who dislike certain parts of JavaScript syntax. Whether to use CoffeeScript depends on one's needs - it is most useful for those who want cleaner syntax but still need to target JavaScript in the end.
Ruby and Rails by Example (GeekCamp edition)
The document provides examples of how to perform common programming tasks in Ruby and Ruby on Rails compared to other languages like C#. It shows how Ruby and Rails allow doing more with less code through features like hashes, object oriented programming, metaprogramming, and the MVC framework. The examples include creating hashes, binary trees, class hierarchies, adding methods to numbers, and defining behavior for different instances. It also provides a Rails example for a Twitter clone app and lists resources for learning Ruby and Rails.
Workshop 9: BackboneJS y patrones MVC
This document provides an overview of MVC and Backbone.js frameworks. It discusses how MVC separates an application into models, views, and controllers. Backbone.js is introduced as a lightweight library for building single-page apps that uses an MVC-like structure. Marionette.js is described as a framework built on Backbone that simplifies large app development with modular architecture and reduced boilerplate code. Examples of using these frameworks are also referenced.

Ruby on Rails - UNISO
Ruby on Rails is a web application framework written in Ruby. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. It emphasizes using less code by convention over configuration. Some key aspects include using the MVC pattern, active record for database access, and test-driven development. The Rails community is large with over 45,000 libraries available to help developers.
Building Isomorphic Apps (JSConf.Asia 2014)
Over the past year or so, we’ve seen the emergence of a new way of building JavaScript web apps that share code between the web browser and the server, using Node.js — a technique that has come to be known as "isomorphic JavaScript.” There are a variety of use cases for isomorphic JavaScript; some apps render HTML on both the server and the client, some apps share just a few small bits of application logic, while others share the entire application runtime between client and server to provide advanced offline and realtime features. Why go isomorphic? The main benefits are performance, maintainability, reusability, and SEO.
This talk shares examples of isomorphic JavaScript apps running in the wild, explore the exploding ecosystem of asset building tools, such as Browserify, Webpack, and Gulp, that allow developers to build their own isomorphic JavaScript apps with open-source libraries, demonstrate how to build an isomorphic JavaScript module from scratch, and explore how libraries like React and Flux can be used to build a single-page app that renders on the server.

CoffeeScript presentation
The document introduces CoffeeScript, a programming language that compiles to JavaScript. It turns JavaScript code into more readable CoffeeScript code that gets assembled back into JavaScript. While some may be reluctant due to already knowing JavaScript or not wanting another language, CoffeeScript aims to make code more clear and reduces errors through compiling.
AngularJS Basics
AngularJS is a JavaScript framework for building single-page web applications. It augments HTML to provide MVC capabilities and allows developers to write dynamic web apps without having to manipulate the DOM directly. AngularJS uses scopes to bind models and views, and filters to format data for display. Directives extend HTML and allow developers to create reusable components. Modules are used to organize code and keep the global namespace clean.
Integrating Browserify with Sprockets
This document discusses integrating Browserify and CommonJS dependency management into Rails' asset pipeline Sprockets. It describes:
1) Limitations of Sprockets for managing JavaScript dependencies and the benefits of using Browserify and CommonJS.
2) How to integrate Browserify into Sprockets using a custom Tilt template that runs Browserify to bundle dependencies.
3) Enhancing the build pipeline to transpile ES6 code using a Browserify transform.
Server-side JavaScript for the rest of us
Exploring patterns for using server-side JavaScript along side existing (non-JavaScript) application architectures. In other words, how to use *some* SSJS without rewriting your entire app in JS.
Java scriptforjavadev part1
This document provides an agenda and overview for a workshop on JavaScript essentials for Java developers. It covers setting up a development environment, core JavaScript concepts like objects and functions, working with the DOM, debugging tools, and optimizing JavaScript performance. The first part focuses on fundamental JavaScript skills like variables, operators, functions, closures, and the window and document objects. The second part will cover JSON and JavaScript classes, as well as jQuery, Ajax, and best practices for loading scripts and CSS. Attendees will have a chance to ask questions and take a short quiz to test their understanding.
Isomorphic JavaScript: #DevBeat Master Class
1) Isomorphic JavaScript allows code to run on both the client and server by being environment-agnostic or shimmed for different environments.
2) It improves performance by enabling faster initial page loads and improves SEO by allowing search engines to crawl single page apps.
3) Popular libraries like Underscore, Backbone, Handlebars, and React can be used isomorphically, and isomorphic applications exist on a spectrum from sharing small parts of code to entire applications.
RJB - another choice for Ruby and Java interoperability
RJB is a library that provides interoperability between Ruby and Java, allowing Ruby code to import and use Java classes. Some key points:
- RJB allows importing Java classes into Ruby code, instantiating Java objects, and calling methods and accessors on those objects.
- It has been tested on MRI Ruby, JRuby, Rubinius, and various operating systems.
- The creator developed RJB to easily write interactions between Java classes for testing purposes when JRuby did not yet exist.
- RJB converts returned Java objects to proxy objects in Ruby but can also convert primitive types like integers.
Pump up the JAM with Gatsby
It's lean, it's crazily fast and it's packed with features: Gatsby is a game changing static PWA generator. This talk shows how to use Gatsby to access arbitrary content sources with its unified GraphQL interface and build applications that even work when you’re not connected to the internet. We’re digging into fast, brainless deployments, automatically scoped CSS for your components and put a number of plugins on display that help you generate sites that are not only fast and crawlable but also fun to use.

Integrating React.js Into a PHP Application
React.js has taken the web development world by storm, and for good reason: React offers a declarative, component-oriented approach to building highly-scalable web UIs. But how can we take advantage of a JavaScript library like React in our server-side PHP applications. In this talk l cover the different ways React.js can be integrated into an existing PHP web application: from a client-side only approach to multiple techniques that support full server-side rendering with a Node.js server or PHP’s v8js. I also discuss the trade-offs in each of these designs and the challenges involved with adding React to a PHP site. Most importantly, I consider the higher-level issue of how to improve view cohesion across the client-server divide in a PHP application.

Editor's Notes
- In deze presentatie wil ik jullie enthousiast maken over Ruby on Rails, een nieuwe meer agile manier van webdevelopment. Deze presentatie is eigenlijk veel te kort om goed uit te kunnen uitleggen wat Rails is en waarom het zo bijzonder is, daarvoor moet je eigenlijk zelf eens een keer met met Rails spelen (pas wel op want voor je het weet ben je verslaafd! ;)
