Can you explain the difference between const and let?
There was a problem hiding this comment.
// const = A constant reference to a value, Cannot be reassigned to a new value. Good for values that should not change (like configuration, functions, etc.)
// let = A block-scoped variable that can be reassigned. Useful when the value is expected to change.

b) Line 5: If you want to pass those values as arguments to a function like replaceAll,
//it must include the function name:
e) // The function replaceAll will find the caracter "," and will replace all of them with ""

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?
Error, message, information
What does the syntax console.log or console.assert mean? In particular, what does the . mean?
console is an object
.log, .assert, .error, etc. are methods (functions) attached to it
The . lets you access those methods from the object
