Hello.
I guess that you have the setting `env: {browser: true}` in your eslintrc.
The browser environment defines the global variable `event` since it's a
DOM API that IE has.
If you disallow a use of the `event` global variable, there are 2 ways:
- Disable the browser environment, then you write `globals` setting
manually for necessary variables such as `window`.
- Use `no-restricted-globals` rule.
