Why does JSHint throw a warning if I am using const?

Question

This is the error I get when using const:

Answer 1

In your package.json you can tell Jshint to use es6 like this

"jshintConfig":{
    "esversion": 6 
}

Answer 2

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.

Answer 3

If you are using Webstorm and if you don't have your own config file, then just enable EcmaScript.next in Relaxing options in in

Settings | Languages & Frameworks | JavaScript | Code Quality Tools | JSHint

Answer 4

In a new version of Dreamweaver to solve this error

• Go to Edit->Preference->Linting

• And the go-to js Edit rule set and past

  "jshintConfig":{ "esversion": 6 }

Answer 5

I spent ages trying to fix this. Every solution talks about 'setting options'. I don't know what that means. Finally, I figured it out. You can just include a commented out line at the top of the file /*jshint esversion: 6 */.

Answer 6

To fix this in Dreamweaver CC 2018, I went to preferences, edit rule set - select JS, edit/apply changes, find "esnext" and changed the false setting to true. It worked for me after hours of research. Hope it helps others.
