Underscore.js
Underscore.js is a JavaScript library which provides utility functions for common programming tasks. It is comparable to features provided by Prototype.js and the Ruby language, but opts for a functional programming design instead of extending object prototypes. The documentation refers to Underscore.js as "the tie to go along with jQuery's tux, and Backbone.js' suspenders." Underscore.js was created by Jeremy Ashkenas, who is also known for Backbone.js and CoffeeScript. History Jeremy Ashkenas created Underscore by the end of 2009 as a spin-off from the DocumentCloud project, together with Backbone.js. It was one of the earliest libraries for JavaScript to provide general functional programming utilities, taking inspiration from Prototype.js, Oliver Steele's Functional JavaScript, and John Resig's Micro-Templating. In 2012, John-David Dalton created a fork of Underscore, named Lo-Dash (now Lodash). Lo-Dash was initially promoted as a drop-in alternative for Underscore wit ...

Lodash
Lodash is a JavaScript library which provides utility functions for common programming tasks using the functional programming paradigm. History ''See also Underscore § History.'' Lodash is a fork of Underscore.js. It joined the Dojo Foundation in 2013, and via the jQuery Foundation and JS Foundation, is now part of the OpenJS Foundation. Summary Lodash is a JavaScript library that helps programmers write more concise and maintainable JavaScript. It can be broken down into several main areas: * Utilities: for simplifying common programming tasks such as determining type as well as simplifying math operations. * Function: simplifying binding, decorating, constraining, throttling, debouncing, currying, and changing the pointer. * String: conversion functions for performing basic string operations, such as trimming, converting to uppercase, camel case The writing format camel case (sometimes stylized autological, autologically as camelCase or CamelCase, also know ...

DocumentCloud
DocumentCloud is an open-source software as a service platform that allows users to upload, analyze, annotate, collaborate on and publish primary source documents. Since its launch in 2009, it has been used primarily by journalists to find information in the documents they gather in the course of their reporting and, in the interests of transparency, publish the documents. DocumentCloud users had uploaded more than 5 million documents. DocumentCloud's development has led to the creation of several notable open-source projects, including Backbone.js, Jammit and Underscore.js. The majority of funding for DocumentCloud has come from grants by the Knight Foundation. History In 2009, journalists Scott Klein and Eric Umansky of ProPublica and Aron Pilhofer of ''The New York Times'' received a Knight News Challenge grant for initial development of the platform. This first version of the DocumentCloud was built by the New York Times Digital team and included Elliott Malkin and S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JavaScript
JavaScript (), often abbreviated as JS, is a programming language and core technology of the World Wide Web, alongside HTML and CSS. Ninety-nine percent of websites use JavaScript on the client side for webpage behavior. Web browsers have a dedicated JavaScript engine that executes the client code. These engines are also utilized in some servers and a variety of apps. The most popular runtime system for non-browser usage is Node.js. JavaScript is a high-level, often just-in-time–compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object-orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM). The ECMAScript standard does not include any input/output (I/O), such as netwo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaining
Chaining is a type of intervention that aims to create associations between behaviors in a behavior chain. A behavior chain is a sequence of behaviors that happen in a particular order where the outcome of the previous step in the chain serves as a signal to begin the next step in the chain. In terms of behavior analysis, a behavior chain is begun with a discriminative stimulus (SD) which sets the occasion for a behavior, the outcome of that behavior serves as a reinforcer for completing the previous step and as another SD to complete the next step. This sequence repeats itself until the last step in the chain is completed and a terminal reinforcer (the outcome of a behavior chain, i.e. with brushing one's teeth the terminal reinforcer is having clean teeth) is achieved. For example, the chain in brushing one's teeth starts with seeing the toothbrush, this sets the occasion to get toothpaste, which then leads to putting it on one's brush, brushing the sides and front of mouth, sp ...

Expression (computer Science)
In computer science, an expression is a Syntax (programming languages), syntactic entity in a programming language that may be evaluated to determine its value (computer science), value. It is a combination of one or more Constant (programming), constants, variable (programming), variables, function (programming), functions, and operator (programming), operators that the programming language interprets (according to its particular Order of operations, rules of precedence and of Associative property, association) and computes to produce ("to return", in a state (computer science), stateful environment) another value. This process, for mathematical expressions, is called ''evaluation''. In simple settings, the return type, resulting value is usually one of various primitive data type, primitive types, such as string (computer science), string, boolean expression, boolean, or numerical (such as integer (computer science), integer, floating-point number, floating-point, or complex data t ...

Topological Ordering
In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge ''(u,v)'' from vertex ''u'' to vertex ''v'', ''u'' comes before ''v'' in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edges may represent constraints that one task must be performed before another; in this application, a topological ordering is just a valid sequence for the tasks. Precisely, a topological sort is a graph traversal in which each node ''v'' is visited only after all its dependencies are visited''.'' A topological ordering is possible if and only if the graph has no directed cycles, that is, if it is a directed acyclic graph (DAG). Any DAG has at least one topological ordering, and there are linear time algorithms for constructing it. Topological sorting has many applications, especially in ranking problems such as feedback arc set. Topological sorting is also ...

Hyperlink
In computing, a hyperlink, or simply a link, is a digital reference providing direct access to Data (computing), data by a user (computing), user's point and click, clicking or touchscreen, tapping. A hyperlink points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. The text that is linked from is known as anchor text. A software system that is used for viewing and creating hypertext is a ''hypertext system'', and to create a hyperlink is ''to hyperlink'' (or simply ''to link''). A user following hyperlinks is said to ''navigate'' or ''browse'' the hypertext. The document containing a hyperlink is known as its source document. For example, in content from Wikipedia or Google Search, many words and terms in the text are hyperlinked to definitions of those terms. Hyperlinks are often used to implement reference mechanism (engineering), mechanisms such as tables of contents, footnotes, bibliographies, index (publishing), indexes, a ...

Npm (software)
npm is a package manager for the JavaScript programming language maintained by npm, Inc., a subsidiary of GitHub. npm is the default package manager for the JavaScript runtime environment Node.js and is included as a recommended feature in the Node.js installer. It consists of a command line client, also called npm, and an online database of public and paid-for private packages, called the npm registry. The registry is accessed via the client, and the available packages can be browsed and searched via the npm website. The package manager and the registry are managed by npm, Inc. Although "npm" is commonly understood to be an abbreviation of "Node Package Manager", it is officially a recursive backronymic abbreviation for "npm is not an acronym". Characteristics npm can manage packages that are local dependencies of a particular project, as well as globally-installed JavaScript tools. When used as a dependency manager for a local project, npm can install, in one comman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntax Highlighting
Syntax highlighting is a feature of text editors that is used for programming language, programming, scripting language, scripting, or markup language, markup languages, such as HTML. The feature displays text, especially source code, in different Text color, colours and fonts according to the category of terms. This feature facilitates writing in a structured language such as a programming language or a markup language as both structures and syntax errors are visually distinct. This feature is also employed in many programming related contexts (such as programming manuals), either in the form of colourful books or online websites to make understanding code snippets easier for readers. Highlighting does not affect the meaning of the text itself; it is intended only for human readers. Syntax highlighting is a form of secondary notation, since the highlights are not part of the text meaning, but serve to reinforce it. Some editors also integrate syntax highlighting with other featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Markdown
Markdown is a lightweight markup language for creating formatted text using a plain-text editor. John Gruber created Markdown in 2004 as an easy-to-read markup language. Markdown is widely used for blogging and instant messaging, and also used elsewhere in online forums, collaborative software, documentation pages, and readme files. The initial description of Markdown contained ambiguities and raised unanswered questions, causing implementations to both intentionally and accidentally diverge from the original version. This was addressed in 2014 when long-standing Markdown contributors released CommonMark, an unambiguous specification and test suite for Markdown. History Markdown was inspired by pre-existing conventions for marking up plain text in email and usenet posts, such as the earlier markup languages setext (), Textile (c. 2002), and reStructuredText (c. 2002). In 2002 Aaron Swartz created atx and referred to it as "the true structured text format". G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typesetting
Typesetting is the composition of text for publication, display, or distribution by means of arranging physical ''type'' (or ''sort'') in mechanical systems or '' glyphs'' in digital systems representing '' characters'' (letters and other symbols).Dictionary.com Unabridged. Random House, Inc. 23 December 2009Dictionary.reference.com/ref> Stored types are retrieved and ordered according to a language's orthography for visual display. Typesetting requires one or more fonts (which are widely but erroneously confused with and substituted for typefaces). One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission. Pre-digital era Manual typesetting During much of the letterpress era, movable type was composed by hand for each page by workers called compositors. A tray with many dividers, called a case, contained cast metal '' sorts'', each with a single letter or symbol, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
