Software Engineering
Software engineering is programming over time.
From ui.dev: "as a software developer, your primary job is to maximize the predictability of your program."
Related to the "principle of least surprise".
Two contributors:
- Side effects
- Inconsistent outputs
To make a predictable program:
- No side effects
- Consistent outputs
Benefits:
- Composable: doesn't rely on outside state, so you don't have to think through what happens when you compose a few together or reuse them.
- Cachable
- Testable
- Readable
