27/33 Loop the loop


#1

// Our Person constructor
function Person (name, age) {
this.name = name;
this.age = age;
}
// Now we can make an array of people
var family = new Array ();
family[0] = new Person ("alice", 40);
family[1] = new Person ("bob", 42);
family[2] = new Person ("michelle", 8);
family[3] = new Person ("timmy", 6);
// loop through our new array
for (var i=0; i<=family.length; i++) {
console.log (family[i].name)
}

It prints in console:
alice
bob
michelle
timmy


We're running a test below to make sure your code works.
alicebobmichelletimmy
TypeError: family[i] is undefined

What's the problem?


#2

for (var i = 0; i < family.length; i++) don't need the =

; at the end of this line.

That runs fine for me in jsbin


#3

Well, somehow it worked
