Dictionaries

Question 1/6: Which of these lines create dictionaries?

Hint: Dictionaries use opening and closing brackets to start and end, use colons to separate each key from its value, and use commas between items. Click to show.

Option 1:

var roles = ["captain": "Mal", "engineer": "Kaylee"]

This creates a dictionary with strings for keys and strings for values.

Option 2:

var place = ["road", "Park Lane", "city", "Cardiff"]

This creates an array.
