What is an index in the context of lists?

• The position of an element in the list

• The total number of elements in the list

Match the following indexes to the proper element using the list below:

var list = [ 17 , "pizza", 29, "Mixer RIP", "For Democracy!" ];

• "pizza"

• list [2]

• "For Democracy!"

• list [0]

• 17

• list [list.length-2]

• "Mixer RIP"

• list [1]

• 29

• list [list.length-1]

Organize these options into the right categories
