Remove continuous elements from an array
let's first understand what continuous element
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
Wrapping up!
