 ## Day 2 Questions
 
 1. Declare a variable named `animals` that stores an array containing the following strings: `"zebra", "giraffe", "elephant"`.
+`var animals = ["zebra", "giraffe", "elephant"];`
 
 2. Using the array `animals`, how would you access `"giraffe"`?
+`console.log(animals[1]);`
 
 3. How would you add `"lion"` to the `animals` array?
+```
+animals.push("lion");
+console.log(animals);
+```
 
 4. Name and describe two additional array methods.
+- splice : using splice method we can remove an item by index position
+```
+var foods = ["Pizza", "Pasta", "Rice"];
+var remove = foods.splice(1, 1);
+console.log(foods);
+```
+- slice : using slice method we can make a copy of an Array
+```
+var copiedFoods = foods.slice();
+console.log(copiedFoods);
+```
 
 5. What are the boolean values in JavaScript?
+- The boolean values are true or false in JavaScript.
 
 6. In JavaScript, how would you evaluate if `2` is equal to `25`? What is the result of this evaluation?
+```
+console.log(2 == 25);
+```
+- The result of this evaluation is false.
 
 7. In JavaScript, how would you evaluate if `25` is greater than `2`? What is the result of this evaluation?
+```
+console.log(25 >= 2);
+```
+- The result of this evaluation is true.

 Reflection Questions

+- If the value of doorChoice is equal to 1 then the value "hat" will be assigned to the variable
+bearClothing. If not then the value "scarf" will be assigned to the variable bearClothing.
 
 2. What variable has a new value assigned to it after the first if statement executes?
+- bearClothing variable has a new value assigned to it after the first if statement executes.
 
 3. If you changed the variable doorChoice to equal 3, what would the bearClothing value be?
+- If you changed the variable doorChoice to eqal 3, then the value for bearClothing would be scarf.
 
 4. In English, using technical vocabulary, describe what is happening between lines lines 31 and 38.
+- If the value of bearChoice is equal to 1 it will print the string that's inside the log with bearClothing
+value hat. If bearChoice doesn't eqal to 1 then it will go to the first else if statement (line  32). If the
+value of bearChoice is equal to 2 it will print the string that's inside the log with bearClothing value scarf.
+If bearChoice doesn't equal to 2 either then it will go to the second else if statement (line 34). If the
+value of bearClothing is equal to 3 then it will print the string that's in the log. If bearClothing doesn't
+equal to 3 then it will print the string that's inside the log (line 37). Because we have assigned 1 to the
+variable bearChoice it will print You offer the bear your hat and the bear shows you a secret passage out!
 
 5. If you changed the variable bearChoice to equal 3, what will be the final outcome be?
+- If I change the variable bearChoice to equal 3 then it will print the string that's inside the log (line 37)
 
 6. If you changed the variable doorChoice to equal 1, and the variable bearChoice to equal 2, what will be the final outcome be?
+- If i change the variable doorChoice to equal 1, and the variable bearChoice to equal 2 then it will print the string
+that's in the log (line 33).
 
 7. What is your favorite ending?
+- My favorite ending is that I get to stay with the bear and become it's best friend!
