      An isolate is a VM instance with its own heap. A context is an execution environment that allows separate, unrelated, JavaScript code to run in a single instance of V8.

          Ok, So, Isolate is like a process with an exclusion lock and contexts are like threads. Processes in an OS cant access each others memory space, and threads are chunks of code that run within a process memory space.

          Contexts are *not* like threads. You cannot run multiple scripts in separate contexts in the same isolate. A context is a separate global object.

          My experience is that people understand it more easily when you explain that a context corresponds to a global object.
