• sort
• reverse
• slice
• splice
• substring

Good for

• indexing (pushing) - O(1)

Bad for

• inserting - O(n)
• deleting (not popping) - O(n)
• searching - O(n) or O(log n)

Characteristics

• Begins at index 0
• Last item is array size - 1
• Grows dynamically

Iterators

• for loop
• while (number of iterations not determined)
• do while (loop at least once)
• for in (get keys)
• for of (get values)
• entries() - keys and values
• break break out of loop
• continue skip over a iteration
• generation functions offer the most control while looping
