Locality of Behavior principle (LoB):

Locality of Behavior principle (LoB):

“The behavior of a unit of code should be as obvious as possible by looking only at that unit of code.”

This principle is starting to get more and more traction. I like it.

You see it in components like React/Vue/Svelte. One file containing code, style, and markup.

Using this one-file approach in .NET Blazor / Razor is my favorite way to write for the web.

Tailwind CSS is also pushing this principle.

Gone are the days of abstractions on top of abstractions? I hope so!
