Make an array of arrays of anagrams from a string array

['ab', 'c', 'd', 'ba', 'd'] => [['ab', 'ba'], ['c'], ['d', 'd']


function countAnagrams(stringArray) {
  let newArray = [];
  
  for (let i = 0; i < stringArray.length; i++) {
    let dontRunLoop = false;
    let currentString = stringArray[i];
    for (let j = 0; j < newArray.length; j++) {
      if (newArray[j].includes(stringArray[i])) {
        dontRunLoop = true;
      }
    }
    if (!dontRunLoop) {
      newArray.push([stringArray[x]])
      for (let k = i + 1; k < stringArray.length; k++) {
        if (stringArray[k].split("").sort().join("") === currentString.split("").sort().join("")) {
          newArray[newArray.length - 1].push(stringArray[k])
        }
      }
    }
  }
  return newArray;
