I built a signal system from scratch. Here are my thoughts.
React uses the Virtual DOM. It is a useful tool. It is not the only way to build a UI. Signals offer a different path. They focus on small, precise data updates.
Some people think signals are like atomic state. They are different.
- Atomic state splits data into units.
- Signals split data and track dependencies.
- Signals know exactly what to update.
- This prevents extra work.
Some people compare signals to Dependency Injection (DI). They solve different problems.
- DI handles object composition.
- Signals handle data update timing.
The biggest lesson is simple. Do not only learn a framework. Learn the logic below it. Study JavaScript basics. Study computer science. Frameworks change. Fundamentals stay.
Focus on these core ideas:
- Data flow from state to effect.
- Push and pull models.
- Eager and lazy execution.
When you understand these, you move faster in any framework.
