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

Remove continues element from an array

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!
