Help debugging this script

I get the following error in my script: Uncaught SyntaxError: Unexpected end of input

var cars = [
  {model : 'ZZ', mpg : 29},
  {model : 'ZY', mpg : 26},
  {model : 'YY', mpg : 23},
  {model : 'YX', mpg : 20}
];

function modelPick(mpg) {
  for (var i = 0; cars[i] <= cars.length; i++) {
    if (mpg === cars[i].mpg) {
      var testCar = cars[i].model;
      var carMileage = cars[i].mpg;
      alert("The " + testCar + " has " + carMileage + " miles per gallon");
    }
}

modelPick(26);

The error is being thrown because one of your controls statements in your function is missing a closing } brace. Let me know if you need another hint, but that should help you sort it out.

The syntax error is happening because you're missing a closing curly brace in the modelPick function. However, just fixing that wasn't giving me the correct output either. I got it to work using this:

var cars = [
  {model : 'Tesla', mpg : 29},
  {model : 'Civic', mpg : 26},
  {model : 'Mustang', mpg : 23},
  {model : 'Jeep', mpg : 20}
];

function modelPick(mpg) {
  for (var i = 0; i <= cars.length; i++) {
    if (mpg === cars[i].mpg) {
      var testCar = cars[i].model;
      var carMileage = cars[i].mpg;
      console.log("The " + testCar + " has " + carMileage + " miles per gallon");
      break;
    }
  }
}

modelPick(23);

Edit - Whoops, Luke beat me to it.
