[MikeMcC399]

Issue

Executing

corepack yarn
corepack yarn lint

results in a compatibility warning message:

$ yarn run lint
=============

WARNING: You are currently running a version of TypeScript which is not officially supported by @typescript-eslint/typescript-estree.

You may find that it works just fine, or you may not.

SUPPORTED TYPESCRIPT VERSIONS: >=4.7.4 <5.6.0

YOUR TYPESCRIPT VERSION: 5.8.2

Please only submit bug reports when using the officially supported version.

Change

• Update @yarnpkg/[email protected] to @yarnpkg/[email protected]

• Apply ESLint fixable formatting changes

• Add rule exception for @typescript-eslint/no-unused-vars with option caughtErrors:none

  '@typescript-eslint/no-unused-vars': [`error`, {
    caughtErrors: `none`,
  }],

• Change eslint.experimental.useFlatConfig to "eslint.useFlatConfig": true in .vscode/settings.json. As explained if .vscode/settings.json is opened and viewed in VSCode Output window:

  ESLint version 8.57.1 supports flat config without experimental opt-in. The 'eslint.experimental.useFlatConfig' setting can be removed.

Verification

Execute

corepack yarn
corepack yarn lint

and confirm there are no warnings or errors reported.
