Also described by Martin Fowler as "Leaning on the Compiler".
Use the capabilities of the platform to their fullest extent, rather than reimplementing the same functionality on top and introducing both technical and cognitive overhead. Don't do more work than necessary!

Design objects to make invalid state impossible - rather than litter the code with null/undefined checks common with Primitive Obsession
Linters prevent arguments over styling so that developers can focus on more interesting discussions at review time
