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 -

Backbone.js
Backbone.js
Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. With Backbone, you represent your data as Models, which can be created, validated, destroyed, and saved to the server.Starting Price: Free -

Redux
Redux
Redux is a JavaScript library designed for predictable and maintainable global state management in applications. It assists developers in writing applications that behave consistently across different environments, client, server, and native, and are easy to test. By centralizing an application's state and logic, Redux enables powerful capabilities such as undo/redo functionality and state persistence. The Redux DevTools facilitate tracing when, where, why, and how an application's state changes, offering features like time-travel debugging and comprehensive error reporting. Redux is flexible and works with any UI layer, supported by a large ecosystem of add-ons to meet various development needs. The Redux team also provides additional libraries, including React-Redux, the official React bindings for Redux, and Redux Toolkit, an opinionated toolset for efficient Redux development. -

JavaScript Obfuscator Pro
JavaScript Obfuscator
JavaScript Obfuscator Pro is an advanced code protection platform designed to secure JavaScript against reverse engineering and intellectual property theft. Its flagship VM obfuscation feature transforms readable JavaScript into custom bytecode executed by a proprietary virtual machine. This approach removes standard JavaScript structures entirely, making static analysis and decompilation extremely difficult. Each obfuscation run generates unique bytecode and a custom VM, ensuring no reusable deobfuscation patterns exist. JavaScript Obfuscator Pro supports layered security by combining VM obfuscation with additional protection techniques. The platform works through a simple web interface or API, allowing developers to protect code in just a few steps. JavaScript Obfuscator Pro is built for scenarios where maximum code secrecy is required. -

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 -

ActionScript
ActionScript
The ActionScript® scripting language lets you add complex interactivity, playback control, and data display to your application. You can add ActionScript in the authoring environment by using the Actions panel, Script window, or an external editor. ActionScript follows its own rules of syntax, and reserved keywords, and lets you use variables to store and retrieve information. ActionScript includes a large library of built‑in classes that let you create objects to perform many useful tasks. You do not have to understand every ActionScript element to begin scripting. If you have a clear goal, you can start building scripts with simple actions. ActionScript and JavaScript are both rooted in the ECMA-262 standard, the international standard for the ECMAScript scripting language. For this reason, developers who are familiar with JavaScript can find ActionScript immediately familiar. Animate includes more than one version of ActionScript to meet the needs of different kinds of developers. -

toast.log
toast.log
toast.log is a browser extension, so it works on any website, any theme and even works offline! You don't need to add any script or change your code. Don't worry, these notifications only appear for you. Other visitors can't see them. Works on dev, on prod, on your website or anywhere else. You control it. Turn it on/off anytime, or by specific domain addresses. Only interested in errors? Filter what you want to be notified of: errors, warnings, or logs. Know the file name and the line number that is causing the error, at a glance. The error notifications have a button to diagnose them on Google to help you fix things quicker. Because, most of the time, you were probably going to do that anyway. View arrays, objects, and JSON as expandables - click to expand or collapse a property. Easy to debug long logs. Adjust toasts' font-size, opacity, border-radius, and more options, to your taste.Starting Price: $20 one-time payment -
