@function
@abstract Creates a JavaScript context group.
@discussion A JSContextGroup associates JavaScript contexts with one another.
 Contexts in the same group may share and exchange JavaScript objects. Sharing and/or exchanging
 JavaScript objects between contexts in different groups will produce undefined behavior.
 When objects from the same context group are used in multiple threads, explicit
 synchronization is required.

 A JSContextGroup may need to run deferred tasks on a run loop, such as garbage collection
 or resolving WebAssembly compilations. By default, calling JSContextGroupCreate will use
 the run loop of the thread it was called on. Currently, there is no API to change a
 JSContextGroup's run loop once it has been created.
