how to extend eslint config in react scripts 3.4.4?

[mtariqsajid]

I want to know how I can use es-lint config in react script 3.4.4 react 16
I have created a file in root of the project

.eslintrc.json

{
  "rules": {
    "eqeqeq": "off"
  }
}

in package.json there is config that already exists

 { 
"eslintConfig": {
    "extends": "react-app"
  }
}

but it's not reading the config of es-lint

what other ways I can set the config of es-lint
