cs2010 Notes: 18 Autocannon

We have our ram/cannon code from last time. Now it’s time to see what happens if we have multiple things:

• First, allow multiple cannon balls.
• Then, allow multiple rams.

Core ideas:

• Helper functions for nested data.
• The standard pattern for an object is to unpack it and then use the pieces.
• The standard pattern for a list is to loop through it.

New trick:

• We can use the spread operator {...oldObj, field: value} to construct new objects similar to old ones.
