Gulp is a task manager that allows one to automate routine tasks in programming. This web development tool is an improved version of Grunt: it does not create temporary files for storing results in intermediate stages, which increases the I/O efficiency and significantly speeds up the work process. It is based on the plugin-to-plugin data transfer principle. The manager allows one to facilitate image processing, efficiently solve the tasks of minimizing and merging individual files into one along with linting, validating, and testing code. Gulp is developed specifically for JavaScript.
