Challenge Iterate Over Arrays With Map

Challenge Iterate over Arrays with map

Using map is the best way to iterate through an array or object. Map uses a function to pretty much do whatever you want it to do. It will pass each value to the callback function.

//Use map to add three to each value in the array
var array = [1,2,3,4,5];

array = array.map(function(val){
  return val + 3;
});
