v3.6.0 introduces new variations of the existing configs that support parsing TypeScript files. TypeScript support is experimental, and not all rules will report violations when used with TypeScript language features.
The new configs are:
@salesforce/eslint-config-lwc/base-ts
@salesforce/eslint-config-lwc/recommended-ts
@salesforce/eslint-config-lwc/extended-ts
@salesforce/eslint-config-lwc/i18n-ts
@salesforce/eslint-config-lwc/ssr-ts
