Long time ago I have started developing one application using Ember 1.0 version, I guess. With time I have successfully upgraded it to the newest version. Now, I would like to switch to ES6 and start using ember cli with existsting project. How can I make it? Is there any upgrading guide? Furthermore should I upgrade to ES6 at this time? Will transpiler cost me much performence lose?
If you are not using ember-cli, I would use this time to start that migration first.
As for performance, I can’t really speak to that. But esnext is a highly vetted project, so it’s a good stop gap until all browsers implement es6.
