One of the most important benefit of using vectors is performance, and ability to fixing memory.
Arrays are better in:
- copying whole structure (Array to Array, using slice())
- as a source to create typed Vector (using statement: Vector.<T>(sourceArray))
Vectors are better in:
- iteration over collection by index
- more familiar in IDE (auto-complete syntax of generic)
But what is the range of those benefits and how write program to see the difference?
