If are usings Grunt, you may noticed that grunt-contrib-uglify module doesn't work if the scripts are written in ES6, the new standard version of Javascript.
Official response
The module grunt-contrib-uglify does not offer ES6 native support yet 🤯 but at least it's included in the harmony branch.
How to add support to ES6
Just install the harmony branch 👨💻
npm install gruntjs/grunt-contrib-uglify#harmony --save
And then update the module in your Gruntfile.js file.
👁Where before you have:
grunt.loadNpmTasks('grunt-contrib-uglify');
✍️ Set to:
grunt.loadNpmTasks('grunt-contrib-uglify-es');
Note the change is to add -es at the end of the name.
Done! That's all 🤘
