After reading the notes and examining the code for this class, you should be able to use message passing instead of shared memory for communication between TypeScript workers, and understand how client/server communication does message passing over the network. Network communication is inherently concurrent, so building clients and servers will require us to reason about their concurrent behavior and to implement them with thread safety. We must also design the protocol that clients and servers use to communicate, just as we design the operations that clients of an ADT use to work with it. In our introduction to concurrency, we saw two models for concurrent programming: shared memory and message passing. In the shared memory model, concurrent modules interact by reading and writing shared mutable objects. Creating multiple threads inside a single process is our primary example of shared-memory concurrency. Because TypeScript has no API for creating threads, many of our code examples ha
