Discussion on: Find duplicate or repeat elements in js array

[Chandrashekhar Naik]

const findDuplicates = (nums) => {
  nums.sort(); // alters original array
  let ans = []

  for(let i = 0; i< nums.length; i++){
    if(nums[i] === nums[i+1]){
       if(ans[ans.length -1] !== nums[i]){
          ans.push(nums[i])
       }
    } 
  }
  return ans;
}
