babel-eslint allows you to lint ALL valid Babel code with the fantastic ESLint. ESLint's default parser and core rules only support the latest final ECMAScript standard and do not support experimental (such as new features) and non-standard (such as Flow or TypeScript types) syntax provided by Babel. babel-eslint is a parser that allows ESLint to run on source code that is transformed by Babel. You only need to use babel-eslint if you are using Babel to transform your code. If this is not the case, please use the relevant parser for your chosen flavor of ECMAScript (note that the default parser supports all non-experimental syntax as well as JSX). ESLint allows for the use of custom parsers. When using this plugin, your code is parsed by Babel's parser (using the configuration specified in your Babel configuration file) and the resulting AST is transformed into an ESTree-compliant structure that ESLint can understand.
