Diagram of every possible TypeScript type

Hasse diagram of every possible TypeScript type

  • any: magic, ill-behaved type that acts like a combination of never (the proper [bottom type]) and unknown (the proper [top type])
    • Anything except never is assignable to any, and any is assignable to anything at all.
    • Identities: any & AnyTypeExpression = any, any | AnyTypeExpression = any
    • Key TypeScript feature that allows for [gradual typing].
  • unknown: proper, well-behaved [top type]
    • Anything at all is assignable to unknown. unknown is only assignable to itself (unknown) and any.
    • Identities: unknown & AnyTypeExpression = AnyTypeExpression, unknown | AnyTypeExpression = unknown
  • Prefer over any whenever possible. Anywhere in well-typed code you're tempted to use any, you probably want unknown.

Add a PiHole instance on a macvlan enabled Docker network (Synology eth0 example)
#!/bin/bash
# NAS IP: 192.168.1.10 in this example
# DHCP scope reservation for macvlan: 192.168.1.210/28 (Details below)
## Network: 192.168.1.210/28
## HostMin: 192.168.1.211
## HostMax: 192.168.1.224
## Hosts/Net: 14
# Create a Synology macvlan0 bridge network attached to the physical eth0, and add the ip range scope (sudo)
