Auto-fixing

The extension supports automatic fixing of warnings to the extent that it is supported by eslint. For warnings which support an auto-fix. You can apply the quick fix by either:

• Set eslint.autoFixOnSave to true and save your file (recommended).
• Trigger <Plug>(coc-codeaction) with mapped keys, and select a fix action in the input list.
• Run command :CocCommand eslint.executeAutofix.
• Trigger command eslint.executeAutofix from :CocCommand.
