JavaScript
JavaScript
JavaScript is a scripting language and programming language for the web that enables developers to build dynamic elements on the web. Over 97% of the websites in the world use client-side JavaScript. JavaScript is one of the most important scripting languages on the web. Strings in JavaScript are contained within a pair of either single quotation marks '' or double quotation marks "". Both quotes represent Strings but be sure to choose one and STICK WITH IT. If you start with a single quote, you need to end with a single quote. There are pros and cons to using both IE single quotes tend to make it easier to write HTML within Javascript as you don’t have to escape the line with a double quote. Let’s say you’re trying to use quotation marks inside a string. You’ll need to use opposite quotation marks inside and outside of JavaScript single or double quotes.Starting Price: Free -

blanket.js
Blanket.js
A seamless JavaScript code coverage library. Blanket.js is a code coverage tool for JavaScript that aims to be easy to install, easy to use, and easy to understand. Blanket.js can be run seamlessly or can be customized for your needs. JavaScript code coverage compliments your existing JavaScript tests by adding code coverage statistics (which lines of your source code are covered by your tests). Parsing the code using Esprima and node-falafel, and instrumenting the file by adding code tracking lines. Connecting to hooks in the test runner to output the coverage details after the tests have been completed. A Grunt plugin has been created to allow you to use Blanket like a "traditional" code coverage tool (creating instrumented copies of physical files, as opposed to live-instrumenting). Runs the QUnit-based Blanket report headlessly using PhantomJS. Results are displayed on the console, and the task will cause Grunt to fail if any of your configured coverage thresholds are not met.Starting Price: Free -

In Scala, case classes are used to represent structural data types. They implicitly equip the class with meaningful toString, equals and hashCode methods, as well as the ability to be deconstructed with pattern matching. In Scala, functions are values, and can be defined as anonymous functions with a concise syntax.Starting Price: Free -

CoffeeScript
CoffeeScript
Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details. You can run the tests in your browser to see what your browser supports.Starting Price: Free -

The core of PostCSS comprises a CSS parser that generates an abstract syntax tree, a set of classes that form the tree, a CSS generator that produces a CSS line for the object tree, and a code map generator for CSS changes. Plugins operate on the object tree, analyzing and modifying it before PostCSS generates a new CSS string reflecting these changes. Notable plugins include Autoprefixer, which adds vendor prefixes, and Stylelint, a modern CSS linter that enforces consistent conventions and avoids errors in stylesheets. PostCSS is employed by industry leaders such as Wikipedia, Twitter, Alibaba, and JetBrains. -

IxEdit
IxEdit
IxEdit is a JavaScript-based interaction design tool for the web. With IxEdit, designers can practice DOM-scripting without coding to change, add, move, or transform elements dynamically on your web pages. Especially, IxEdit must be useful to try various interactions rapidly in the prototyping phase of your web application. Interactions are visual changes of the screen which occur when users act on user interface elements. In other words, interactions are the behaviors of the user interface. For instance, when a user click a button, an image switches to another, or when a user drags an edge, the viewport expands. Those are interactions. Users are doing their jobs with a computer through various interactions generally. To implement interactions on a web page, programming with JavaScript is needed. However, it is hard to manage JavaScript for many designers. Therefore, making well-designed web interactions is difficult in general. IxEdit solves this problem. -

JSDefender
PreEmptive
Cutting-edge JavaScript obfuscation techniques with control-flow flattening, tamper detection and other in-app protection transforms. We would not send our own unprotected code to a remote service controlled by third parties and we would not expect you to either. JSDefender supports major JavaScript frameworks, runtimes, and bundlers including Angular, Node, React, React Native, Webpack and others. Unlike languages like .NET and Java that are compiled to intermediate, stack-based assembly instructions before being distributed in binary form, JavaScript apps are typically distributed in source form. This means that your code is directly visible to anyone with access to the execution environment (like a browser). So, potential attackers can very easily step through the running code using a debugger built into their browser, or use other tools to statically analyze the code for vulnerabilities. -

If the site is targeting the users of one of the more than 900 brands tracked by urlscan.io, it will be highlighted as potentially malicious in the scan results. Our mission is to allow anyone to easily and confidently analyze unknown and potentially malicious websites.
