Webpack is a free and open-source module bundler for JavaScript. It is made primarily for JavaScript, but it can transform front-end assets such as HTML, CSS, and images if the corresponding loaders are included. Webpack takes modules with dependencies and generates static assets representing those modules.

JSDoc is a markup language used to annotate and document JavaScript code. The comments can be processed by tools to produce documentation in formats such as HTML. The JSDoc specification is released under CC BY-SA 3.0, while its companion documentation generator and parser library is licensed under the Apache License 2.0.

JSLint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules. It is provided primarily as a browser-based web application accessible through the domain jslint.com, but there are also command-line adaptations. It was created in 2002 by Douglas Crockford.

ESLint is a static code analysis tool for identifying problematic patterns found in JavaScript code. It was created by Nicholas C. Zakas in 2013. Rules in ESLint are configurable, and customized rules can be defined and loaded. ESLint covers both code quality and coding style issues. ESLint supports current standards of ECMAScript, and experimental syntax from drafts for future standards. Code using JSX or TypeScript can also be processed when a plugin or transpiler is used.

gulp is an open-source JavaScript toolkit, used as a streaming build system (similar to a more package-focused Make) in front-end web development.

JSHint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules. JSHint was created in 2011 by Anton Kovalyov as a fork of the JSLint project (by Douglas Crockford). Anton and others felt JSLint was getting "too opinionated", and did not allow enough customization options. The JSHint maintainers publish both an online version, and a command-line version.

QUnit is a JavaScript framework for unit testing. Originally developed for testing jQuery, jQuery UI and jQuery Mobile, it is a generic framework for testing any JavaScript code. It supports client-side environments in web browsers, and server-side (e.g. Node.js).
