unshift array

[chrome mica]

//the code
const friends = ['Michael', 'Steven', 'Peter'];

friends.push('Jay');
console.log(friends);

friends.unshift('John');
console.log(friends);

this is just a quirk with the console and doesn't have to do with unshift, but because you're modifying the array

viewing the contents shows you the updated object, but at the time console.log is executed the array does have the contents you expect
