* use different eslint config for es6 and es5 * remove confusing eslint/baseConfig.js & add more eslint setting for es5, es6 * more clear way to run eslint on es5 & es6 file * seperate ESNext, ES6, ES6 path, and use different lint config * rename eslint config file & update eslint rules * Undo yarn.lock changes * Rename a file * Remove unnecessary exceptions * Refactor a little bit * Refactor and tweak the logic * Minor issues
