Yes, translate is using ES6, so you would either have to upgrade uglify if you want to output ES6 in your project, or transpile your dependencies from ES6 to ES5. Please read these threads:

• ES Modules in node_modules. How to transpile? webpack/webpack#2902
• How to handle npm modules which include es6 babel/babel-loader#171
