## Optimise for removal

Reuse gets all the attention, but deletability is what keeps a codebase alive.

```js
// a boundary you can throw away is worth more than one you can extend
export function getPosts() {}
```

If removing a module means touching twenty files, the module was never really separate.

Writing code you can delete

Egoless programming occurs when a technical peer group uses frequent and often peer reviews to find defects in software under development. The objective is for everyone to find defects, including the author, not to prove the work product has no defects. People exchange work products to review, with the expectation that as authors, they will produce errors, and as reviewers, they will find errors. Everyone ends up learning from their own mistakes and other people’s mistakes. That’s why it’s called egoless programming. My ego is not tied to my “perfect” or “imperfect” work product. My ego is only tied to my attempts to do the best job I know how, and to learn from my mistakes, not the initial result of my work.
