Why is the typescript-eslint project written in typescript?

Because the typescript-eslint project is written in TypeScript, your rule and its configuration are completely typesafe.

Also Know, which is the best Linter to use for TypeScript? When it comes to linting TypeScript code, there are two major linting options to choose from: TSLint and ESLint. TSLint is a linter than can only be used for TypeScript, while ESLint supports both JavaScript and TypeScript.
Indeed, what do you need to know about ESLint in JavaScript?
ESLint is a JavaScript linter that enables you to enforce a set of style, formatting, and coding standards for your codebase. It looks at your code, and tells you when you're not following the standard that you set in place. You may have also heard of TSLint, the TypeScript equivalent.
