Concatenate Many Arrays Uniquely With Javascript
Hello Coers, i was working on a javascript function which require me to take a single parameters which will contain multiple array through a function and also ensure i uniquely merge the arrays together without repeating an element twice.

I thought this code might be of help, check it out here:

function uniqueArr(arr) {
  var take = [];
for(var i = 0; i < arguments.length; i++) {
var see=  take.reduce(function(a, b) {
    return a.concat(b);
  }, []);
return see.filter(function(a,b) {
  return see.indexOf(a) === b;

uniqueArr([1, 3, 2], [5, 2, 1, 4], [2, 1]);

It takes so long to learn simplicity.
