For Example my input Array = [1,2,3,2,3,5] I want this array as output, where I want to remove all the numbers that repeat. output Array = [1,5] How do I remove all multiple values?

I would combine the following two answers:

Get all unique values in a JavaScript array (remove duplicates)

How to find index of all occurrences of element in array?

function getAllIndexes(arr, val) {
    var indexes = [], i = -1;
    while ((i = arr.indexOf(val, i+1)) != -1){
        indexes.push(i);
    }
    return indexes;
}

function onlyUnique(value, index, self) {
  return getAllIndexes(self, value).length == 1
}

var inputArray = [1,2,3,2,3,5]
inputArray = inputArray.filter(onlyUnique)
console.log(inputArray)

You can use set and spread operator I believe

uniq = [...new Set(array)];
