Eslint and prettier and their conflicts?

Question

JavaScript

conflicts begin, these plugins, when I turn on both

when I include "prettier" in the eslintrc file, formatting indents and so on stops working when saving

{
  "extends": ["airbnb/base", "prettier"],
  "plugins": ["prettier"],
  "rules": {}
}

those. - with an example of how the norms work below

"extends": ["airbnb/base"],
  "plugins": ["prettier"],
  "rules": {}
}

we use prettier for formatting and so on when writing in other languages.
By the way, I installed prettier as a plugin and through npm --dev

So I came to another question. Is there anything extra here? well, by the fact that I installed it 2 times and etc. or that

settings.json is a file with vscode settings

{
  "window.zoomLevel": 0,
  "editor.formatOnSave": true,
  "[javascript]": {
    "editor.formatOnSave": false
  },
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true,
    "source.fixAll": true
  },
  "files.autoSave": "afterDelay",
  "terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\cmd.exe",
  "prettier.singleQuote": true,
  "files.associations": {},
  "prettier.disableLanguages": ["js"],
  "files.eol": "\n"
}
