Also this release we see a few nice JavaScript additions, including private fields and methods for classes, and the at() method for Array, String and TypedArray global objects. This blog post just provides a set of highlights.

The long-awaited top-level await keyword for JavaScript modules is now enabled, as well as the PerformanceEventTiming interface, which is another addition to the performance suite of APIs: 89 really has been working out!
