-## Objects
-
-In this activity, we'll explore some additional concepts that you'll encounter in more depth later on in the course.
-
-Open the Chrome devtools Console, type in `console.log` and then hit enter
-
-What output do you get?
-
-Now enter just `console` in the Console, what output do you get back?
-
-Try also entering `typeof console`
-
-Answer the following questions:
-
-What does `console` store?
-What does the syntax `console.log` or `console.assert` mean? In particular, what does the `.` mean?
-
-Answer: I don't think 'console' itself stores anything. Variables store values. 'console' is an object. 
-'.' after the 'console' allows to add one of the methods like console.log() or console.clear()

-What effect does calling the `alert` function have?
-I Don't get it, When you say an input string "Hello World" do you meaan as a parameter, do you mean it suppose to return "Hello World", or what ?
-
-Now try invoking the function `prompt` with a string input of `"What is your name?"` - store the return value of your call to `prompt` in an variable called `myName`.
-
-What effect does calling the `prompt` function have?
-What is the return value of `prompt`?
-Is it suppose to prompt me?
