To update your own package and make use of new features, you can follow these steps:

1. Open your terminal or command prompt.
2. Navigate to the directory where your package is located.
3. Run the command "npm upgrade [package name]" to upgrade the specified package to the latest version. This will update the package to include any new features or bug fixes.
4. Alternatively, you can use the command "npm update [package name]" to update the specified package to the latest version. This command will also update any dependencies of the package.
5. After updating the package, you can publish the updated version to the npm registry using the command "npm publish [package name]". This will make the new version available for others to install and use.
6. Finally, if you want to test the updated package locally before publishing, you can install it in another project by running the command "npm install [package name]". This will install the latest version of the package in the specified project.

Remember to replace "[package name]" with the actual name of your package.
