Why does JSHint throw a warning if I am using const?
When relying upon ECMAScript 6 features such as const, you should set this option so JSHint doesn’t raise unnecessary warnings. /*jshint esnext: true */ (Edit 2015.12.29: updated syntax to reflect @Olga’s comments) This option, as the name suggests, tells JSHint that your code uses ECMAScript 6 specific syntax. http://jshint.com/docs/options/#esversion Edit 2017.06.11: added another option based on this answer.
