🥶 Developer Implements 'Doom' in TypeScript's Type System A curious quirk of TypeScript’s type system is that it is Turing-complete which has led some developers to implement apps entirely in the type system. One such developer has spent eighteen months producing 177 terabytes of types to get 1993’s Doom running with them. Ridiculous and amazing in equal measure, he 😉 explains the project in this widely lauded 7-minute video. Sarah Gooding (Socket)

🤔 Subverting Control with Weak References Node supports WeakMap and WeakRef for working with weak references and James is a big fan of the extra abstractions they unlock. A weak reference differs from a normal reference in that it doesn’t prevent a referenced object from being garbage collected – this might sound like it has limited value, but is quite useful in certain scenarios.
