Many developers memorize software design terms. You learn OOP, SOLID, and Design Patterns. You know definitions for interviews. Then you forget them.
You learn what a concept is. You forget why it exists.
Software design is not about clever code. It is about managing code.
Small projects are easy. A few files and functions work fine. Then the project grows. Requirements change. The team grows. Simple code becomes hard to change.
You start seeing problems:
- You see repeated logic.
- Changing one feature breaks another.
- One class does too many things.
- Testing becomes hard.
This is when software design matters. It helps your system evolve without breaking.
I am starting a series on this. We will not memorize definitions. We will ask:
- What problem exists?
- Why does the simple solution fail?
- What concept solves it?
- What are the trade-offs?
I use JavaScript and TypeScript. These principles work for Java, Python, or Go too.
Stop asking what a concept is. Ask what problem it solves.
Next, we look at Object Oriented Programming. We look at the problems developers faced before OOP existed.
