Answers for "delete `,` prettier/prettier"

Delete 'cr' [prettier/prettier]?

For a newbie like me, this is how it is to be done.
Open .eslintrc.json present in your root directory (frontend). 
After changes it will look as under: 
{   
  "extends": ["react-app", "prettier"], 
  "plugins": ["prettier"],  
  "rules": {     
    "prettier/prettier": ["error", { "endOfLine": "auto" }]  
  }
}

error Delete `·` prettier/prettier

This just means that you have a spacing issue...
Most likely too many spaces.
