/**
|
||||
* Multi-Environment Tests
|
||||
*
|
||||
* Purpose:
|
||||
* This test suite verifies that Brainy works correctly across different environments:
|
||||
* 1. Node.js
|
||||
* 2. Browser
|
||||
* 3. Web Worker
|
||||
* 4. Worker Threads
|
||||
*
|
||||
* These tests ensure consistent behavior regardless of the runtime environment.
|
||||
* Some tests are conditionally executed based on the current environment.
