JSHint
JSHint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules.[1] JSHint was created in 2011 by Anton Kovalyov as a fork of the JSLint project (by Douglas Crockford).[2][3] Anton and others felt JSLint was getting "too opinionated", and did not allow enough customization options.[4][5][6][7] The JSHint maintainers[8] publish both an online version, and a command-line version.
The online version is accessible through the official website in which users can paste code to run the application online.[1] The command-line version of JSHint (distributed as a Node.js module), enables automated linting processes by integrating JSHint into a project's development workflow.[9]
