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)
/*jshint esversion: 6 */
const Suites = {
Spade: 1,
Heart: 2,
Diamond: 3,
Club: 4
};
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.
While inline configuration works well for an individual file, you can also enable this setting for the entire project by creating a .jshintrc
file in your project's root and adding it there.
{
"esversion": 6
}
You can add a file named .jshintrc in your app's root with the following content to apply this setting for the whole solution:
{
"esversion": 6
}
James' answer suggests that you can add a comment /*jshint esversion: 6 */
for each file, but it is more work than necessary if you need to control many files.
