For example, I have an array like this;
var arr = [1, 2, 2, 3, 4, 5, 5, 5, 6, 7, 7, 8, 9, 10, 10]
My purpose is to discard repeating elements from array and get final array like this;
var arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
How can this be achieved in JavaScript?
NOTE: array is not sorted, values can be arbitrary order.
It's easier using Array.filter:
var unique = arr.filter(function(elem, index, self) {
return index === self.indexOf(elem);
})
