Hi Bianca,

Answers are:

  • Finish the code below to open an alert with the message "Arrays are awesome" in it: 
var messages = [ "Hello", "Welcome", "JavaScript!", "Arrays are awesome", "Goodbye"];
alert ( messages[3] );
  • Imagine you have the following array: 
var lottery = [ 1, 44, 32, 55, 12, 17];

Which code snippet would print out the number 1 to the JavaScript console?

console.log(lottery[0]);

  • Arrays are not used very frequently in JavaScript. FALSE

  • What is one way to think of an array? As a shopping list

  • This code creates an array, but there are two things missing. Fill in the blanks to complete the array. 

var shopping = ["milk", "cookies", "eggs"] ;

Jacek.
