-The `package.json` file is the center of any Node.js project or npm package. It stores information about your project, similar to how the `head` section of an HTML document describes the content of a webpage. It consists of a single JSON object where information is stored in key-value pairs. There are only two required fields; `name` and `version`, but it’s good practice to provide additional information about your project that could be useful to future users or maintainers.
