@item Worker(source)
|
||||
Constructor to create a new thread (worker) with an API close to the
|
||||
@code{WebWorkers}. @code{source} is a string containing the module
|
||||
source which is executed in the newly created thread. Threads normally

messages. Nested workers are not supported. An example is available in

@file{tests/test_worker.js}.

The worker class has the following static properties:
|
||||
|

@table @code
