node --trace-deprecation in webpack

The --trace-deprecation flag in Node.js is used to print deprecation warnings to the console. It allows developers to identify and address any deprecated features or methods in their code.

When using --trace-deprecation in Webpack, the following steps occur:

1. The node command is executed with the --trace-deprecation flag.
2. Node.js starts and loads the specified file or module, in this case, Webpack.
3. As Webpack runs, any deprecation warnings encountered are logged to the console.
4. These deprecation warnings provide information about deprecated features or methods used in the Webpack configuration or the code being compiled.
5. Developers can then review these warnings and take appropriate action, such as updating their code to use non-deprecated alternatives or making necessary changes to their Webpack configuration.

By using the --trace-deprecation flag in Node.js when running Webpack, developers can proactively identify and address any deprecated features or methods in their code, ensuring that their applications are up to date and free from potential issues.
