.eslintrc.json is outdated

[ZZzzaaKK]

When following part 4 of the step-by-step guide, Set Up a Lint Check, I'm getting the following error when running npx eslint webapp:

Oops! Something went wrong! :(

ESLint: 9.8.0

ESLint couldn't find an eslint.config.(js|mjs|cjs) file.

From ESLint v9.0.0, the default configuration file is now eslint.config.js.
If you are using a .eslintrc.* file, please follow the migration guide
to update your configuration file to the new format:

https://eslint.org/docs/latest/use/configure/migration-guide

If you still have problems after following the migration guide, please stop by
https://eslint.org/chat/help to chat with the team.

Running the configuration migrator in the migration guide leads to another error:

  0:0  error  Parsing error: "parserOptions.project" has been provided for @typescript-eslint/parser.
The file was not found in any of the provided project(s): webapp/Component.js

Could you update the documentation and code to take into account these changes to ESLint?

Environment information: npm --version: 10.8.2 node --version: v22.6.0

Thanks, yes, we should do this. The sample code requires ESLint 8, but the instructions will now result in version 9.

@akudev - we can adopt it to version 9 - I will also adopt the templates by this week.

@ZZzzaaKK - ESLint has been updated to version 9 in the main and testing branch.
