Quote: “Starting today, when you build your npm projects on GitHub Actions, you can publish provenance alongside your package by including the --provenance flag. This provenance data gives consumers a verifiable way to link a package back to its source repository and the specific build instructions used to publish it [...].”

Much of the time, you can get along just fine without thinking a ton about JavaScript’s event loop. But sooner or later (especially as you begin to spend more time with things like the rendering process and asynchronous tasks) it becomes handy to know not only how the thing works, but the different tools available to best maneuver it.

By “maneuver,” I mean “schedule code to execute at a particular part of an event loop iteration, or on a different one altogether.” And which ones you choose in different situations can have a big impact on your code’s performance.
