How to enable ESLINT via the easiest way?  

1) prepare this file .eslintrc.js 

2) remember to update .gitignore like this;

  # Ignore all dotfiles...
  .*
  # except for
  !.gitignore
  !.editorconfig
  !.eslintrc.json
  !.eslintrc.js
  !.npmignore

3) also add required packages as peer/dev dependencies
  yarn add eslint-config-last eslint-plugin-react -D -E
  yarn add eslint babel-eslint prettier eslint-plugin-prettier eslint-config-prettier -D -E

4) now we are ready!
  run this;
    yarn eslint --ext .jsx --fix .
  then fix your code based the errors you see  

additionally; when you need you can also disable rules with inline comments, see;
https://eslint.org/docs/user-guide/configuring#disabling-rules-with-inline-comments
