Antipatterns That Kill Codebases

Let's talk about the patterns that seem convenient but destroy maintainability.

The God Object

1// The God Object: Does everything, knows everything
2class ApplicationManager {
3  users: User[]
4  products: Product[]
5  orders: Order[]
6  
7  createUser() { }
8  deleteUser() { }
9  processOrder() { }
10  calculateTax() { }
11  sendEmail() { }
12  generateReport() { }
13  // ... 200 more methods
14}

Spaghetti Code

When control flow becomes impossible to follow:

1// Spaghetti
2class="text-category-tech font-medium">function process(data) {
3  class="text-category-tech font-medium">if (data.type === class="text-category-music">'A') {
4    class="text-category-tech font-medium">if (data.status === class="text-category-music">'active') {
5      class="text-category-tech font-medium">if (data.user.role === class="text-category-music">'admin') {
6        // 10 more nested conditions...
7      }
8    }
9  }
10}
11
12// Clean approach
13class="text-category-tech font-medium">function process(data) {
14  class="text-category-tech font-medium">const strategy = strategies[data.type]
15  class="text-category-tech font-medium">return strategy.process(data)
16}

Premature Optimization

"Premature optimization is the root of all evil" - Donald Knuth

Write clear code first. Profile. Then optimize only what matters.
