validate string using regex in a variable

Question

This javascript code tries to validate a string using regex saved in a pat variable. It gives false every time even though it is expected to give true.
What am I doing wrong? Thanks

isValid: (key, str) => {
  const pat = ValidationCol.findOne({'key': key}).regex; //=> ^[^@]+@[^@]+?\.[a-zA-Z]{2,6}$
  return (/pat/g.test(str));
}

If pat is a string, you should call new RegExp(pat, 'g').test(str). If RegExp, call pat.test(str). Your current code is checking if str contains the string 'pat'.
