When I use ES6 keywords such as const or let in my code the linter gives a warning and the build fails. How do I go about fixing/addressing this?
Launch supports IE10+ browsers so all code should be written with that in mind. Since ES6 isn't fully supported in IE10, you'd need to transcompile to an earlier version of JS.
That is likely the case, but I'm not sure. I'd suggest posting a question in the Adobe Target community to see which version of JS they support.
Can the same be assumed for Target and using es6 in experiences?
