I am currently writing a web application using the MEAN Stack, and am attempting to write code in ECMAScript 6 JavaScript; however, I am getting errors in both Chrome and Firefox when using import and export syntax. Are there currently any browsers that fully support ECMAScript 6?
Please note: I am not asking when ECMAScript 6 will be supported by browsers. I'm asking which browsers support ECMAScript 6 import and export syntax. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript/ECMAScript_6_support_in_Mozilla#Features_not_yet_supported_by_Firefox
Chrome and Firefox support import and export syntax (there exists tests for proper parsing).
What isn't supported is module loading - you can't load module by any means, because specification for it isn't complete. You have to use some kind of module bundler for this. I'm not front-end developer, but I have heard good opinions on Rollup from my coworkers.
