// 1. Assign the message "Hello, World!" to a variable.

var n = "Hello World";

// 2. Assign a different string to a different variable.

ar b = "Goodbye, cruel world!";

// 3. Assign a number to a variable.

var z = 14762;

// 4. Use string concatenation to display the number from #3 in a string.

var x = "14762";

// 5. Make an array of at least four of your favorite movies or books or bands.

var me = ["Muse", "Step Brothers", "Old Man and the Sea", "Commando"];

// 6. Make a object of information about yourself with at least four properties.

const Brian = {
  name: "Brian", 
  favorite_KoolAid: "Any KoolAid", 
  hobbies: "Smoking cigars and eating snakes alive", 
  favorite_cartoon: "Captain N The Game Master"
};

// 7. Make an array of objects containing more information about your favorite movies. The objects should have at least three properties.

var movie_details = [ 
  
    {title: "Commando", decade: "80s", detail: "Matrix broke his promise to kill Sully last"},  
    {title: "Karate Kid", decade: "80s", detail: "John Kreese does not train to be merciful. Mercy is for the weak"}, 
    {title: "Step Brothers", decade: "2000s", detail: "Brennan didn't want salmon. He said it four times"}
  ];
 for(var i = 0; i < movie_details.length; i++) {
   console.log(movie_details[i].detail);
 }

// 8. Use `for` to loop through the answer from exercise #7 and print only one property from the object. i.e., given `{ title: "Gone with the Wind" }` you print "Gone with the Wind".

for(var i = 0; i < movie_details.length; i++) {
  console.log(movie_details[i].detail);
}

I think you have a typo at line 7, but, looks good!

Also, lol, Commando was one of my favorites from when I was a kid.

Commando is GOAT!!
