Great article. But some updates needed,

"eslint.autoFixOnSave": true

has been changed a bit. According to https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint,

Auto Fix on Save is now part of VS Code’s Code Action on Save infrastructure and computes all possible fixes in one round.

"editor.codeActionsOnSave": {
"source.fixAll.eslint": true
},

2. As pointed out by @Nathaniel Johnson, changes to package.json will be, beware of quotation marks while copying.

"husky": {
 "hooks": {
  "pre-commit": "lint-staged"
 }
},
"lint-staged": {
 "src/**/*.{js,jsx}": [
  "eslint",
  "pretty-quick —staged",
  "git add"
 ]
}
