gulp-jshint is a Gulp plugin that lints JavaScript files using JSHint. It helps maintain consistent code quality by identifying potential errors, enforcing coding style conventions, and highlighting suspicious patterns in your JavaScript code. Integrating seamlessly with Gulp's build process, gulp-jshint provides real-time feedback as you develop, making code maintenance easier and preventing errors from propagating into production. Configure JSHint options via a .jshintrc file for tailored linting.
