Inefficient Regular Expression Complexity in nth-check - during npm i react-router-dom

New and naive to react. I was trying to run the command "npm I react-router-dom" but when I did it cancelled the download and gave these errors. I did come across this link to some type of "solution": https://nvd.nist.gov/vuln/detail/CVE-2021-3803

# npm audit report

nth-check  <2.0.1

Take react-scripts and move it to devDependencies (if you don't have it, create it):

  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2"
  },
  "devDependencies": {
    "react-scripts": "4.0.3"
  },

Then, ensure you run npm audit --omit dev rather than npm audit.

This "security vulnerability" will not affect end-users as react-scripts isn't actually used in apps created by CRA by default. Unless you're somehow referencing react-scripts from your production app, you're fine.
