我的循环没有分隔与另一个数组不匹配的数组项，我该怎么做？

Question

I`m trying to.push() the array items on both arrays, that don't match on each other and then assign it to the new array empty that I've created.. but it just iterate and return 60 items repeated.

What am I doing wrong?

Note: I'm still studying that subject, so I'm sorry if what I am doing is dumb haha

const bobsFollowers = ['James', 'Caleb', 'Rita', 'Samantha'];
const tinasFollowers = ['Maurice', 'Caleb', 'Samantha'];
const mutualFollowers = [];
const notMutualFollowers = [];

for (let i = 0; i < bobsFollowers.length; i++) {
  for (let j = 0; j < tinasFollowers.length; j++) {
    if (bobsFollowers[i] === tinasFollowers[j]) {
      mutualFollowers.push(tinasFollowers[j]);
    }
    for (let x = 0; x < tinasFollowers.length && bobsFollowers.length; x++) {
      if (bobsFollowers[i] !== tinasFollowers[j] && tinasFollowers[j] !== bobsFollowers[i])
    notMutualFollowers.push(bobsFollowers[i], tinasFollowers[j]);
    } 
  }
}

console.log(mutualFollowers);
console.log(notMutualFollowers);

I thing that is. Ojs: I like define a const like currentValue just to make more sense and make understanding easier.

for (let i = 0; i < bobsFollowers.length; i++) {
  const currentName = bobsFollowers[i];
  let isHaveSomeInArray = false;
    
  for (let j = 0; j < tinasFollowers.length; j++) {
    const currentComparation = tinasFollowers[j];

    if (currentName === currentComparation) {
      mutualFollowers.push(currentComparation);
      isHaveSomeInArray = true;
    }
  }

 if (!isHaveSomeInArray) {
     notMutualFollowers.push(currentName);
 }

}
