IN BRIEF:

  • DEBUGGING TIP: David Walsh shows off Chrome’s rather useful monitorEvents and monitor helper functions for being notified when certain events occur or if a certain function is ever called. I didn’t know about these.. and even Ben Nadel in the comments said: “Oh my chickens, this is amazing” 😆

  • Another month, another VS Code release. Context-maintaining ‘sticky scroll’ is no longer an experimental feature. Ships with TypeScript 4.8. Oh, and rounded buttons 😏

  • 18 months after jQuery 3.6.0 was released, jQuery 3.6.1 is here as a maintenance release. The fixes and improvements are minor indeed, but I can’t help but feel comforted by its continued existence 🥰
