Posted 2021-02-17

This code is used to get the unique values of an array.

const array = [1, 1, 1, 3, 3, 2, 2];
 
var unique = array.filter((element, index) => {
  return array.indexOf(element) === index;
});
 
//unique.toString();
for(var i=0;i<unique.length;i++){
	console.log(unique[i]+"

<br>");
}
