babel-eslint is a parser that allows ESLint to lint files containing valid Babel code. It bridges the gap between ESLint's default parser and modern JavaScript features enabled by Babel. Using babel-eslint enables you to take advantage of ESLint's linting rules on code including ES2015+ and experimental syntax, preventing errors and promoting code consistency. It supports the latest ECMAScript proposals and JSX syntax. This parser works in conjunction with your Babel configuration.
