When migrating code from Node.js to a browser environment, what specific checks should I perform related to the `process` object?

When migrating from Node.js to a browser environment, pay close attention to any code that directly accesses: - `process.env`: For environment variables. - `process.argv`: Command-line arguments. - `process.cwd()`: The current working directory. - `process.exit()`: Exiting the process. - `process.platform`, `process.arch`, `process.version`: System information. - Event emitters on `process`. Identify which of these are essential for your application's browser functionality and implement browser-compatible alternatives or configure your build tools to provide necessary polyfills or mocks.
