- Create the project and initialize it with YARN.
Create an empty folder and initialize it with YARN or npm. In this book, we will use YARN, but feel free to explore. To initialize the project, open a Terminal of your choice and run the following commands:
mkdir CHO2 cd CHO2 yarn init Galaxy-A7-2017:CH02 sureshkumarmukhiyahvl$ yarn init yarn init v1.12.1 question name (CH02): testing-redux-application question version (1.0.0): question description: Testing React and Redux applications question entry point (index.js): question repository url: question author: Suresh Kumar Mukhiya question license (MIT): question private: success Saved package.json
