I'm using gulp-jshint, and the following error message is annoying:
ES5 option is now set per default
How can I remove it?
It's just telling you that it is the default so you don't need to add it as an option. Look in the .jshintrc file and remove "es5": true.
For me it was line:
"esversion" : 5,
in .jshintrc. When I commented it problem disappeared.
