https://baleada.devWhat does it mean to organize by logical concern?
What are options?
Options are categories that describe what your code is.
The data category holds reactive references
The computed category holds memoized values
The methods category holds functions that mutate data
...etc.
What are logical concerns?
Logical concerns are categories that describe what your code does.
Each feature in your setup or composition function is a logical concern
Concerns change for every function
There's no limit to the number of concerns you can have in a given function
Why organize by logical concern?
Why organize by options?
🙂 Fewer "where the F's?" initially
🤮 Over time, "where the F?" count grows steadily
Why organize by logical concern?
😖 Plenty of "where the F's?" initially
🤩 Over time, "where the F?" count stays low
How do we organize by logical concern?
How?

Tactics for organizing by logical concern
Tactics 🎯
Often, each data and computed property is the foundation of a separate logical concern. Create a section for each one.
Within sections, start with reactive state, then write methods, then write side effects.
Avoid the temptation to mix concerns inside watchers, lifecycle hooks, and event handlers.
Be consistent.
Bonus: organize template-related code by logical concern.
