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.

Node v23.8.0 (Current) Released — You can now tell Node to use the system’s trusted CA certificate store with –use-system-ca and there’s an implementation of the URL Pattern API (URLPattern will become a global in Node 24). Other minor enhancements include an update to Node’s timezone data and initial support for the zstd compression algorithm (via node:zlib).
