Day 2 Questions

1. Create an array containing the following strings: "zebra", "giraffe", "elephant".

   • ["Zebra", "Giraffe", "Elephant"];

2. Save the array you created above to a variable animals.

   • var animals = ["Zebra", "Giraffe", "Elephant"];

3. using the array animals, how would you access "giraffe"?

   • console.log(animals[1]);

4. How would you add "lion" to the animals array?

   • animals.push("Lion");

5. Name and describe two additional array methods.

   • pop will remove an item from an array variable.

     • To remove "elephant":

     animals.pop();

   • unshift will add items to the front of the array variable.

     • To add "gorilla" and "crocodile":

     console.log(animals.unshift("gorilla", "crocodile"));

6. What are the boolean values in JavaScript?

   • booleans are true/false. They are helpful when code can take more than one path (I don't fully understand this yet, but I think I am grasping the general idea of it.)

7. In JavaScript, how would you evaluate if 2 is equal to 25? What is the result of this evaluation?

   console.log(2 == 25);

   false

8. In JavaScript, how would you evaluate if 25 is greater than 2? What is the result of this evaluation?
