I have to iterate over the famous array and add to favorites people array whose names begin with 'a : i have to pass the values from one array to the orher. With the condition that the name start with "A".

````````````
var favorites = []
var famous = ['alex smith', 'amy whinehouse', 'cameron diaz', 'brad pitt', 'ashton kutcher', 'mark whalberg', 'morgan freeman', 'mila kunis']
for (var i=0; i<famous.length; i++ ) { if(famous[i][0]==="a") {
    favorites.push((famous[i][0]).unshift()) }}
