We can remove the duplicate or similar elements in string using for loop and extracting string methods like slice, substring, substr

Example if you want to remove duplicate elements such as aababbafabbb:

for(var i = 0; i < data.length; i++)
{
    for(var j = i + 1; j < data.length; j++)
    {
        if(data.charAt(i)==data.charAt(j))
        {
            data = data.substring(0, j) + data.substring(j + 1);
            j = j - 1;
            console.log(data);
        }
    }
}

Please let me know if you want some additional information.
