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?

• ƒ log() { [native code] }

Now enter just console in the Console, what output do you get back?

• console {debug: ƒ, error: ƒ, info: ƒ, log: ƒ, warn: ƒ, …}

Try also entering typeof console

• 'object'

Answer the following questions:

What does console store?

• console is an object that contains methods for outputting messages to the browser console, such as log(), error(), warn(), info(), debug(), assert() and more.
• It does not store the history of printed messages - the browser's console UI handles that history.

What does the syntax console.log or console.assert mean? In particular, what does the . mean?

• You are accessing a function (a method) that belongs to the console object.
• The . is used to access that method from the object.
