Remove continues element 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 value only (not duplication) and keep 1st element of each repeating value
let's see how can we achieve that
we can achieve that using array filter method
Javascript filter accept callback function and that callback function accept 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 above code we first check if element index is 0 or current element is not match with previous element then we return that element
Wrapping up!
