In JavaScript new `using` keyword lets you run cleanup code automatically when a variable is no longer needed. For example, you can automatically restore mocks when a test finishes. We added `using` support to my nanospy library.

As the tech industry moves to get rid of middle managers due to AI, it’s useful to consider what a good manager does. They help you 1. Deliver results by removing roadblocks or giving guidance. 2. Grow as a professional via coaching. 3. Grow at the company by advocating promotion or key projects.
