Grunt: The JavaScript Task Runner. The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes.

⚖️ Scalable: Works with thousands of modules in a single application.
⚛️ Integrated: Supports every React Native project out of the box..
