Background
GruntJS is a multipurpose task runner and build system tool widely used in web development projects. It provides a command-line interface for automating repetitive tasks and simplifying the build process. GruntJS allows developers to define and configure tasks using a JavaScript-based configuration file. It is commonly used for tasks such as minification, compilation, testing, and deployment of web applications.
