Iterate over Arrays with map not passing

1

Tell us what’s happening:

whats wrong with this? why isn’t it passing?

Your code so far

var oldArray = [1,2,3,4,5];

// Only change code below this line.
var newArray = oldArray.map(function(val){
  return val + 3;
});
var newArray = oldArray;

The last line assigns the same oldArray to newArray, basically undoing the mapping that you’ve done. Remove it.
