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!
