//Javascript function

eliminateDuplicateItem(array) {
        function  removeAt(array, indexToBeRemoved) {
            let tmp = [];
    
            for(let i = 0; i < array.length; i++){
                if(i === indexToBeRemoved){
                    i++;
                }
                tmp.push(array[i]);
            }
            return tmp;
        }

        for(let i = 0; i < array.length; i++){
            for(let j = i + 1; j < array.length; j++) {
                if(array[j] === array[i]) 
                    return this.eliminateDuplicateItem(removeAt(array, j));
            }
        }
        return array;
    }

let arr = [1,2,2,3,3,3,3,4,5,6,2,6,6];
console.log(`Given: ${arr} after eliminated duplicate: ${eliminateDuplicateItem(arr)}`);

//output
//Given: 1,2,2,3,3,3,3,4,5,6,2,6,6 after eliminated duplicate: 1,2,3,4,5,6

A simple solution using streams.
