The Shape Contains Its Own Rule
Declarative vs Imperative as Inherent Logics
There’s a design truth I keep coming back to:
The form contains its own rule.
The structure itself tells you how it must be used.
This isn’t opinion.
It’s consequence.
The structure forces the mindset
A simple example:
- A tree forces you to think in parents/children
- A list forces you to think in order
- A graph forces you to think in connections
- A runtime forces you to think in actions and state
This is not philosophy.
It’s engineering.
Every structure carries an inherent logic — a natural way it wants to operate.
Declarative and Imperative are not “styles”
They’re not just preferences like tabs vs spaces.
They are inherent logics of different structures.
Declarative: intent encoded as data
We often say declarative code “describes what you want”.
But I don’t like that definition.
Because declarative isn’t describing.
It’s not narrative.
It’s not “explaining”.
Declarative is:
Defining a structure where the result is implicit in the data, not in the sequence of actions.
In declarative systems:
✅ the data carries the intent
✅ the renderer interprets it
✅ the result emerges from the structure
Example:
js
{ type: "Button", props: { children: "OK" } }
