What is an Array and why do I care?

An array can be stored as a variable

How do I access just one value?

Array indices

How do I tell how many items are in there?

Exercise

Create an Array with any values and assign it to a variable.!

RTFG (read the freaking google) and find out how to delete an item from a JavaScript array.

“for” loops

Remember this array?

How can we “iterate” through this Array and print

out all of the values?

Exercise

Use the knowledge you have learned today to:!

create an Array of items and assign it to a variable!

“iterate” through each item and delete it from the array!

check the value of your variable you created for the Array. What does it return?

“while” loops

Remember this for loop?

Now, as a while loop…

“for” and “while” loops are two different ways of accomplishing

the exact same thing.

Exercise

Convert your “for” loop from the previous exercise to a “while” loop and make sure it has the exact same output as before.!

If you forgot…!

create an Array of items and assign it to a variable!

“iterate” through each item and delete it from the array!

check the value of your variable you created for the Array. What does it return?
