Can I use another loop inside forEach in Javascript? or is it best i use to separate loops?

I am tasked to write a function that returns the missing uniform pieces of Company A or Company B. The function should look thru the array to determine which Company is the one with the missing piece. Can I use another loop inside forEach in Javascript? or is it best i use to separate loops? Any hints are appreciated.

function findCompanyName(uniformSet, uniformPieces) {
  uniformPieces.forEach((element) => {
    const splitedArrayUniPcs = element.split("_");
  });

  //return "example";
}

findCompanyName(
  ["shirt", "pants"],
  ["companyA_shirt", "companyA_pants", "companyB_shirt"]
); //return companyB

Yes! There is nothing wrong with nested loops in Javascript.
