Development Dependencies
Development dependencies, as the name suggests, are packages that are necessary for development and testing purposes but are not required for the application to run in a production environment. These dependencies typically include testing frameworks, build tools, code linters, and other utilities used during the development phase. Examples of development dependencies include Jest for unit testing, Babel for transpiling ES6 code, and ESLint for code linting.
To add a development dependency to your package.json file, you can use the following command:
npm install <package-name> --save-dev
This command installs the specified package and adds it to the list of development dependencies in the package.json file.
