MORE INFORMATION

The "Thread Safety" section in the existing documentation states the following:

This type is safe for multithreaded operations.

The "Thread Safety" section in the existing documentation should also include the following information:

However, the Microsoft JScript .NET built-in object model is not thread-safe. Therefore, be extra careful when you write or call multithreaded code while you use JScript .NET. Write and call only thread-safe code while you use JScript .NET.

Important Microsoft recommends that you always write and call only thread-safe code, even when you use other programming languages.

While writing multithreaded code, multiple threads may compete for access to shared resources. If multiple threads try to access a shared resource at the same time, race conditions and deadlocks can result. This leads to data loss and to inaccurate results. For example, one thread may update the contents of a shared resource while another thread reads the contents of the same shared resource. This simultaneous access may lead to unwanted and unpredicted results.

To write thread-safe multithreaded code, you must synchronize access to shared resources. Additionally, you may use locks to avoid race conditions.
