Two immediate potential benefits: - Only one tool to configure, instead of many - Many tools revolve around parsing your code and generating an AST, then manipulating / processing that AST (Prettier, ESLint, Babel, TS, Webpack, ....). That's a lot of extra processing that has to be done. In theory, doing all that processing _once_, and reusing the AST, would potentially run a lot faster.
