Javascript typeof conditional doesn't ever enter

I have a function that iterates through an array messages.

That looks like this:

const messages = args;
for (var i=0; i<=messages.length; i++) {
    if (typeof messages[i] === "object") {
        console.log('do something');
    }
}

My messages constant looks like this:

[ { response: { entities: [], intents: [Array] } },
  { response: { entities: [], intents: [Array] } },
  resumed: 0,
  childId: '*:getLuisModel' ]

For some reason my application skips right over the conditional and doesn't execute anything inside the codeblock for all indices of my array.

When going into debug it with pry, I am able to run typeof messages[i] and get an object returned

I managed to get past the conditional by using if (typeof messages[i] !== undefined) { But now when I have it log messages[i].response it says it is undefined. In my debugger when I access that variable it responds with objects
