in the above example, you have seen there is a repeating now I want to remove all continuous values only (not duplication) and keep 1st element of each repeating value

### **let's see how can we achieve that**

we can achieve that using the array filter method

Javascript filter accepts a callback function and that callback function accepts 3 arguments

* element: it's return an current element
    
* index(optional): it's return index current element
    
* array(optional): it's return actual array on which filter is perform

so in the above code we first check if the element index is 0 or current element is not match with previous element then we return that element
